[bendrew]

I just bought the upgrade for video hoster now and i cannot upgrade saying installed in many computer. This is a fact that everytime i install the upgrade, i'm having this problem. Not only me, even my friends, too. They always ask my help of upgrading it. Most of them come to my house to do the upgrade. I don't know what kind of system Mtu have but it's not fair. Do i have to cancel my upgrade purchase or what. Need help on this one. Remember, this always happen... that's why i'm reluctant to upgrade....
