Lost library, importing groups from endnote web

I restarted my computer and stupidly agreed to save my endnote library when it started, which was an empty library- thus deleting all my 304 references and many groups.  Fortunately I was able to import my references from endnote web to recover them.  I can not figure out how to import my groups as well… is this possible?

You can instead of importing your references from EndNote online use the Sync feature with a new library to pull down your references and groups from EndNote online:

Create a brand new library and click the Tools menu > Sync.

You would click OK to the warning message and it will start to download from EndNote online to populate the library.

If this does not work or you have other questions:

I have accidentally deleted my groups from Endnote Web version.

Is there any way I can restore those deleted groups?

(restoring the general folder, with unclassified articles was possible, but not the groups, which contained sorted out articles)
