Extra information:

Can't open 'E:/GENIUS DENIED BB/noncgi/Forum52/upgrade.txt'.

The server has told me that the disk is out of space - I was prevented from writing to the file.

Please ask the administrator to contact the web hosting provider.

The exact error returned by the operating system is:
No space left on device


***BUT
The disk has 45GB of free disk space - any ideas?
