Unfortunately another DDOS attack, but has been filtered out now.

mining works fine

well, at least it's not complaining about a missing file anymore - progress

Try using cd to go to the path that contains oclvanitygen.exe first, then run oclvanitygen.exe.  It's probably using your "c:\Users\username\" as the working dir, and thus not seeing the file.

If you're using the binary that Remember remember the 5th of November shared via dropbox, it doesn't include the calc_addrs.cl file, you need to get that from the main vanitygen download zip.
