I'd like to give ProM 6 a spin, but unfortunately it won't start as it should. Running prom6.bat, it gets the packages.xml downloaded OK regardless of proxy, but it then fails when trying to set up UITopia:
WARNING: No configuration found for UITopia!
(This is okay if you start the application for the first time)
Creating new configuration file at C:\Profiles\XXX\UITopia\uito...
Exception in thread "main" java.lang.NullPointerException
The folder C:\Profiles\XXX\UITopia is created, but that's it - no contents ever appear inside it. :-(
