Lost customized output style after laptop died

Hi everyone, here is my issue :

I am writing a PhD thesis using EndNote. I created my own citation style, which included renaming certain reference types.

My laptop died recently.

I have now installed EndNote on a new laptop, logged into my account, and syncronized my library.

I also had a copy of my EndNote file from the previous laptop on a USB key. I was able to import the custom style I had created from the USB key to my library on the new laptop.

Issue 1: Missing RefTypeTable.xml?

However, when I check the imported style, it looks nothing like it did on my old laptop.

My understanding is that this happens because I need to access the special RefTypeTable.xml file which stores the changes I made to the reference types ; and apparently this file is only stored locally on my old laptop; I cannot find it in the EndNote file I saved on my USB key. Is this correct? If so, is there a way to retrieve it without the old laptop?

Issue 2: Citation Formatting Inconsistencies

More importantly, I am facing an issue with citations in my thesis Word document.

All existing footnotes remain correct according to the custom style.

If I insert a citation to a reference that was already in my library before my laptop died, the formatting also follows my custom style - even though, when I check the style settings in my new EndNote installation, they don’t match the actual citation output in the Word document.

This makes it impossible for me to check or correct potential formatting issues in my thesis since the style displayed in EndNote does not match the actual output.

However, when I insert a citation to a new reference, even if I carefully match its fields with a similar existing reference, the citation formatting is incorrect, i.e., it does not follow my custom style. Instead, it seems to follow a modified version of my custom style, as it currently appears in my library, without all the changes I made.

So I can’t add new references and insert citations in a way that matches my previous citations.

Does anyone understand what is happening here? Is there a solution to restore my custom reference type mappings and ensure consistency?

Thanks in advance for your help!
