Nice to see you here, Dr.
The Mission Editor works fine on my PC while IMFViewer keeps crashing, weird hmm? I found out this program was from Slovenia and I tried to used MS AppLocale to run it, this time it didn't crash at the start but still end up with an "execption that couldn't handle".
I'm eager to known if there is any other way to convert IMF files? It seemed to be long before I could get Viewer working.
