I'm trying to use Depositfiles a lot, and I keep getting this error:

Attention!

Downloading is currently impossible, because the link generated for your IP address xx.xxx.xx.xxx is now obsolete, please, get a new download-link

If you consider this to be a mistake, please send the following message to our support department.
incorrect session downloading

Any one know how I can stop this?

In return:
