Vista Users: If you're a vista user you might need to have your UAC (User Account Control) disabled.
How to disable UAC:
1. Go to control panel (Press start -> Control Panel)
2. Click "User Accounts and Family Safety"
3. Click "User Account" and at the bottom you should see "Turn User Account Safety on or off" now click that.
4. Now uncheck the box and press "Ok" then restart. If it's already unchecked then it's already disabled.
Compatibility (Vista):
Before opening the MPGH 1.05.exe right click it first then click "Properties" -> "compatibility" and set the compatibility mode to "Windows XP SP2" then press "Ok".
Then right click MPGH 1.05.exe then click "Run as Administrator"
Anti-Virus Problems:
AVG Anti-virus - If you're using this antivirus you need to have this disabled before opening the MGPH Pub 1.05.
If you don't want to disable your AVG antivirus you could download another free antivirus here:
Avast Antivirus: avast! 4 Home Edition - FREE antivirus software - Download
Bitdefender: Free Antivirus - BitDefender Free Edition
New members: The MPGH Pub 1.05 hack requires you to have a MPGH forum account and atleast 1 post to get the hacks to work so you must need to meet the requirements if you haven't so..
