processing tiles failure?

[fishboy73]

I am trying to get through the self mentoring process on vassal and have some experience with vassal albeit only through solitaire play. I have downloaded the main uber ap and enabled  the two extensions.  However, whenever I load the uber ap in Vassal it never completes the processing tiles step. just stays at 0%. I can still  get into the module and play out the first scenario and make a even make a log file.  However if I try to play back the log file it fails saying data is missing. Any advice would be appreciated.  Thanks in advance.
