"Compressed Library" command freezes Endnote X3

Hello everyone,

I’m trying to create a new library file out of some of my references, and I understand that the best way to do this is to create an .enlx file using “Compressed Library” from the File Menu. However, every time I try to do this, Endnote simply freezes, and I have to force quit the program.

I want to compress about 144 refs, but I tried to trouble shoot by compressing only 10 refs into a file and that froze the program as well. It freezes whether I try to include attachments with the refs or not.

I have Endnote X3 for Mac. Does anyone know where the trouble might lie?
