no file uploading

i tried to upload a file into my account on wuala the encryption starts and does well but after that wuala uploads nothing

i tried this now several times (1 week before it worked well) and dont find a clue to the problem i tried to use wuala directly and also tried the smb drive in windows both show the same behaviour of not uploading

the only thing that have changed is that my online time is now 20 % and i got some extra space from wuala does this can have anything to do with the problem ??

greetz keep up the great work
