Return of Reckoning

I have downloaded the torrent files, and used the patcher for all the files. Game doesnt seem to let me log in. I decided to delete it all then re install it all and now this error comes up. What is it?

Error: System.IO.IOException: The process cannot access the file 'C:\Users\Mike\Desktop\Warhammer Online - Age of Reckoning\art.myp' because it is being used by another process.

Check that you removed the write protection on the your war hammer directory and subdirectories
Also but a bit obvious check disk not full

I had this issue, aaaaaand the problem was that I had left my torrent download on seeding for the client.... Which seems a little counter-intuitive but hey that's life sometimes. Bada bing bada boom baby!
