Hi Steve
I am not able to help you, but I am having exactly the same issue since 08.082008. Worked fine initially and now I cannot open any document anymore, even though the LiveCycle Designer ES 8.2 itself runs. When trying importing any pdf or create a new one, it gets me through step by step, but as soon as it should display the document, it gets the Windows message that it stopped working.
I already spend hours in uninstalling and reinstalling. I also tried to change the DEP (Data Execution Prevention) so Windows would not shut it down. No success so far.
I am using Vista Ultimate and installed the LiveCycle as a part of Acrobat 9 Pro Extend.
If anyone has an idea, I would also appreciate it.
Rolf
