Request Editor hangs-soapUI Pro 4.0.1

I created a new project in soapUI Pro 4.0.1, the program hangs when trying to open the Request Editor. The Request Editor opens fine in soapUI 4.0.1 free version without any problem for the same project. All other projects are working fine in soapUI Pro 4.0.1.

Here are errors that are repeated until killing soapUI Pro after it hangs. I found this in the soapui.log file. No other logs appeared to be updated during the problem.

These are the last two entries (out of many of the same error) from the soapui.log
