Hi,
I'm having a weird problem here.
Every time I want to create moviesheets for my movies/series with ThumbGen, I get a file not found error, whether the movie file is on the local drive or on my WDTV HDD (via netshare, preferred way).
Granting administrator privileges for ThumbGen won't help, as well as the Automatic Mode, with which I don't get exact two errors (one for each moviesheet) but rather about 20-40.
The error looks like this:

Translation: "The file "C:\Users\Der Sven\AppData\Local\Temp\[...] could not be found".
But: Both moviesheets are created in exact this folder! The only problem seems to be... they are created with a completely different hexagonal filename than in the errormessage.
My path is actually named "C:\Benutzer\...", but normally Windows translates into this when called with "C:\Users\..."
What could I be doing wrong? Thumbnail, folder.jpg and .nfo are being created without an error, btw.
