Thank you very much for your elaborate answers, explanations and corrections.
The manufacturer put in a new motherboard, and to my wish a new larger HD. My two HD’s before the crash still are available for me, though I only can attach the one or the other as slave next to the new one.
Indeed I’m confused about the terminology (and even inaccurate) of styles, types and whether refer to what I see when and where…
If I go into the Preferences and choose for Output Styles, I can edit my self made Reference Type, referreing to my R.ens file. Although this file is said to be modified on July 21, 2006 it seems to be a Style that is based on Show all, but contains nothing what I have been editing until July 25, 2006.(The terminology used by EN does really confuse me).
If I go into the Preferences pane and choose Reference Types, then I can remember that I created two reference types derived from Journal Article and gave them a name. But here I’m confused again: If I look at the roll down selection after Default Reference Type, then I see at the bottom Unused, Unused 2 and Unused 3. However, if I select Modify Reference Types… in the EndNote Preferences pane I see a similar vertically organized table having RefType names right of Generic, not quite synchronized with the list in the roll down selection menu mentioned before. I remember, though, that I edited one or the two Unused (or Unused 2) columns to make my own attribute names that would be used with either of my own created reference types. Are they (or should the be) the same as the names shown in the drop down list behind Default Reference Type, or do I mix up things? I have tried many times to fathom the structure of how EN works with these entities, but I seem to miss the meaning of the terms used in EN.
From your suggestions I think that I could try the following, but I cannot judge whether this is too tricky:
On one of the HDs there must be (a back up of) my former system registry, that could be examined, or could I even use regedit on a different place, namely the one at the slave? I more or less understand what’s told in the link that Leanne gave.
CrazyGecko suggested to regain the folder locations of the Style, Filter and Connection Folders, but I only couldn recap the location where I stored all my EndNote libraries. But! herewith I seem to found back my Display Fields!
But If I restart EndNote, I don’t see my only recovered RefType.ens file any more, or more specific this RfType was, but is not present anymore since I changed file locations and restarted EndNote… And, there are no Unused Deault Reference Types, neither there are any Display Fields in my reopened Reference Library that uses the .ens-file and the Display Fields found back previously (i.e. before restarting EN). I can open my library because it’s in the sub menu ‘recently used libraries’, but if I choose Ctrl-O I’m directed to the place in Program Files/EndNote where I can see Connections, Examples, Filters, Palm, Spell, Styles, Templates and Term Lists, with a fresh date of change, but not my recently closed library… It’s still a mess, I think.
I don’t understand your 3rd paragraph to save things, but that’s a serious thing to be done if everything is sane again.
I’m glad that Myoshigi understood my unclear explanation of my problems, and, as I stated, I must have a back up from my old registry. But you say that reference type information was saved, but not the custom made reference types. I really don’t understand what is the difference between reference type information and information about reference types that were custom made. Where’s the border?
I sincerely hope, from what I have written down here, makes sense to help me further, if possible!
