rapidshare upload problems

I occasionally have problems with the rapidshare uploader -- and perhaps this is mostly on the weekend (???). It will get close to uploading the first file in a group that I've put into the uploader, then stop working, and give me various error messages in German at the bottom left of the software window -- usually "Listenindex" full or something like that. The software indicates that it has tried to reconnect to rapidshare but can't. I'm wondering if this is an issue with rapidshare (to reduce uploading ...) or with my ip. This has wasted a lot of my computer's time, as I've put a list of stuff in the uploader for overnight uploading, and got none of it up!!!

Anyone else had similar problems? Any clear solutions?

The software I'm using has all messages in English. Did you download this tool from rapidshare.com or rapidshare.de? (I'm using the rapidshare.com one, and so far haven't had any problems.)
