Some of you have reported that the Adrive service is not working. In attempting to download from Adrive a message appears suggesting that the service is overloaded ("Public File Busy").
Inspection of the number of downloads shows that no downloads at all are possible from Adrive. I have reported this to Adrive, and am awaiting their answer.
I will re-upload some of the more recent files to another server. If you want to download an older file on Adrive, please report this to me (for example by commenting on this post). I will subsequently upload that file to another server.
UPDATE Mat 30, 2011: Adrive reports that the issue has been resolved. I have checked this with a few files and everything seems to be in good working order now.
