Error Message--hard to understand...

Hello Technician Friends,

I'm getting ready to start my dissertation and I am unable to get my Sync feature to work on one of my lap top computers...I have updated all of the sync preview software and the zotero program (as well) but still it doesn't sync on one computer.

Here is the error message that I get:
#1921233418
[JavaScript Error: "[Exception... "'[Exception...
