Could you enable logging and set it to full profile level, and post those logs.
Please try to answer all the questions asked. This is a volunteer board, and I only have limited time to assist. The more information you can provide, the better I can help.

Have you contacted their tech support?
If so, ask if they wrote their own code, or if they are using someone elses, that may help us diagnose.
