[PookayG]

I have Zt2 ultimate collection and it did not work on my pc , I called microsoft for help.-1-800-microsoft, they help for free for zt2 ultimate collection, but they did not solve my problem but found out that my computer was crashing for all sorts of reasons, He suggested that i do a system recovery on my computer, this WORKED, I installed the game again and it work, I suggest that u do a back up file first before you begin....GOOD LUCK ps get help with this if you dont know how to do this.
