NNA software error (in win2000 pro)

Currently my credit union is running NNA software (notary training software). Whenever a user tries to run the software they get the following error:

TB80RTM caused an access violation in TB80RMT.dll at 0x5433cf5e
Click on close to terminate this application
Click on ignore to continue You should save your work in a new file.

I have uninstalled and reinstalled the software. I also updated windows and all the drivers. I made sure that the security settings for the NNA software was set to everybody. I am stuck and don’t know where to go. Please help.
