Endnote X7 library not opening in Endnote X8

Hi there

I have  both the data and enl files in the same place. Since moving to X8 when I attempt to open the libary it ‘hangs’ for a bit then says Endnote error.

Here is what I have tried to do:

Removing temp files

Recovering library (only recoverd 11 or the 191 references within it.

Moving files and creating a new ENL file and recovering.

Any tips?
