I am experiencing some issue with JChem for Excel. It has been working fine with the latest version (14.8.1100.592x86) until this morning. Although JChem for Excel loads into Excel and the correct tab is present, when I click on any of the functions from the JChem tab (incl. help and licenses), all the functions become disabled and greyed out. No structure are displayed on the Excel spreadsheet.
There are no obvious disabled add-ins. I have tried to downgrade to an older version that is working for one of my colleague (18.104.22.1681.x86) but I have the same issues.
Running Windows 7, Office 2010, Version 14.0.7128.5000 (32bits)
