Best Regards How Winbloze calculates whether or not you have to purchase a new license is how "different" your hardware upgrade is from your original hardware. Certain parts collect more "points" and contribute more towards it forcing you to buy a new license. A motherboard and CPU are pretty much what make a computer a computer, so I'm willing to bet that you'll need to buy a new license and activate again. But I don't *think* you'll have to "reinstall", maybe just reactivate with a new license. Extremely easy to get around it though. But of course, you shouldn't do it because it's wrong and Santa will put you on his bad boy list. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
