I've been using ABBYY in my app for a few months now. I believe I might be under the 5000 installs limit but does the expiration of my license crash the app for new users? I recently sent in my app update for review to the app store and the crash logs they sent me pointed to the line where i'm loading the license file. It seems to be working perfectly in my phone but seems to be crashing for the app reviewers.
I'm just thinking could this be one of the reasons, that's all. :)
