hi all, 1. 5 or 6 months ago i purchased windows 7 ultimate box (both 32-bit and 64-bit). i installed the 32 bit version on my notebook 2 or 3 times without any problem. then 1 week ago, i decided to use 64 bit and installed succesfully. but when it comes to activation, it doesn't. the error message is `the product key is expired`. i'm in libya now and don't know how to solve this problem really. 2. i'm planning to sell my notebook and buy a new one in a few months. i'll install my 64 bit on new notebook but if i get the same error again, i'm sure i'll hate microsoft and never buy a microsoft product anymore. i need your experiences please, and much thanks in advance.
