Looks like someone else had similar issues as you but nobody answered back in this thread: http://forums.adobe.com/thread/621797?decorator=print&displayFullThread=true
I found the following thread http://forums.adobe.com/message/3951627#3951627. If you look at the last comment made by Steve.Madwin, he explains the process of CRL validation with Adobe Acrobat. I don't know if this helps you or not troubleshooting. If anyone has steps, please let us know. Thanks.
I've read both links above. The first post is still unanswered. The second sounds a bit different than mine. Steve.Madwin does explain the porcess of CRL validation well but there isn't really a solution to the issue I'm experiencing. I'm still having this issue. I'm able to successfully sign documents using the same cert within MS Word and spreadsheets within MS Excel on the same machine.
I'm really surprised nobody else has anything to say on this topic and I can't believe I can't find any solutions in Google regarding this issue. Stumped.
I called Adobe support. Apparently my company has volume licensing but do not have any support associated so I have to go with the free support option. I'm totally bummed out as I doubt I'm going to get anyway. If anybody out there experienced this issue before, your response will be greatly appreciated!
Working with Tier 2 and still outstanding. Does anyone have any insight to share please?
