How do i remove my user information completely from my device?

You simply need to email support for this.

Hi, please consider adding the SIZE of the download to the " more info". This will impact if I use my precious 3G connection which is faster but not unlimited vs. waiting until I have a slower but free wifi connection. Had an issue trying to download my MHC purchase over 3G. I did not realize the file was HUGH. After using over 50 mb of my precious data your app crashed and it took me back to zero! I then had to drive to a free wifi location and the download stalled or produced an error after 3 attempts over 30 mins!! I finally gave up. Will need to try again over my faster 3G when my data plan renews. Pretty frustrating. There is NO reason why you can't post the SIZE of these files.:(
