I have tried to follow the WINME OEM AS UPGRADE guide on the site but i can't get it to work.

it says Rename the WIN.COM and WINVER.EXE, if i do it within windows i still get the error telling me to buy the upgrade version. If i do it in MSDOS then i can't load windows - so can someone talk me through how to upgrade sucessfully and as risk free as possible. Thanx a lot for your help.
