General Support: Plogger logs me off when trying to import

Hey everybody,
I'm sorry if this has been discussed before, I didn't find anything about my problem.
The title says it all, I upload my photos, then go to administration, into import section, I select what I want etc, then click Import and I get logged off (and the pictures are not imported).
Please help me with this, plogger is a great system, but I just can't solve this. And, by the way, I changed the language (that means I edited a few words in some files), but I'm pretty sure I didn't do anything wrong there.

Thanks in advance
