I set up iTunes Match on my iMac at home last night and everything went well. I set up my iPhone and it is working fine. When I try to set up iTunes on my Windows 7 work computer, I turn on iTunes Match and it says all of my songs are available in the cloud. However, they never appear in my library and iTunes freezes up and stops responding. I've tried restarts, shutdowns and reinstalling iTunes, but it still keeps freezing. Anyone else have this happen. Any suggestions on how to fix? Thanks.
