I am reading this almost exactly three years after the original post...
The original post describes my problem exactly. I'm in Vista, and LC shuts down with an error message after opening a document almost immediately. LC also shuts down if I try to open and edit the document from Acrobat or create a new document.
I am using LC version 8.2 and I cannot locate the file at
C:\Documents and Settings\username\Application Data\Adobe\Designer\8.2.
I know Vista elimianted the DS file and the former "Application Data" is now "Program Data", but I cannot locate a "... Designer\8.2" file.
As always, any help would be greatly appreciated before I pull my hair out, or call customer service and pull my hair out.
I have a few screenshots here that show Windows XP and Vista: http://forums.adobe.com/message/2226510#2226510.
In addition it is the same location for Windows 7:
