Itunes Match wont let me add my computer as a device
Ok, so i have a pc and there are 4 user accounts and my mom made me download her "purchased music" so i did. One day iTunes Match was acting up so i turned it off and then back on(my Computer(PC)) and then it wouldnt let me add the computer because it says this computer is already associated with an Apple ID. So now i cant use itunes match like before it wont load my playlists i can still upload songs using my imac but that wont load my playlists either. SO I DONT KNOW WHAT TO DO BECAUSE I HAVE TO 62 DAYS BEFORE I CAN ADD COMPUTER TO ITUNES MATCH
ANY SUGGESTIONS
iPhone 4, iPhone 4s
