Have been having a serious issue with ACA 2008. Everything will be working fine, then I will start ACA and get the following message : "Catalogue file C\Documents and settings \ mike \ Application Data \ Autodesk \ ACD-A 2009 \ enu \ Support \ AcFields.fdc not found ". I click OK and the screen comes up with no menus or pulldowns. All the palettes come up and I can access dwg files from the project browser, but none of the tool palettes work. Repair and re-install don't work: the only way I have found to remedy this is to uninstall ACA and then do a new install. Has anyone come across this before ? I tried with a normal User and does'nt work. I tried User with PC's admin rights and nothing: doesn't work! I can't launch program outside the Domain of our corporation. Any help muchly appreciated!!!
