The DLL error open up when I try to open JJM tools, whereas this is what happens when I try to open JJM itself (on win7):

In C:\Program Files(x86)\TSF\JJM\JJMConfig.ini kann nicht geschrieben werden.
Which means that JJM (or some1/something) can't write in this .ini file.

Got any clues as to why? I'll go for a re-install, cuz JJM worked fine right after I'd launched it from the installer itself.
