iTunes Match problem!

[taylor200588]

I have a really complicated problem with my iTunes match that hopefully someone will understand and know how to help. I have iTunes Match on my macbook, iPhone and iPad. I recently done a complete system restore and updated to mountain lion (which i think isnt the problem) and restored all my music back via time machine. Now, when I go into my iTunes match it tells me that my computer already has an user linked to it and I have to wait 90 days for something. So I've signed into my account and nothing, tried to deactivate and reactivate the authenticity of my account to iTunes match but nothing, I went into my managed devices and the two device linked to my Match is my iPhone and iPad.

So I cant upload any new music or anything via my mac but I think I can with my iPhone or iPad if I purchase anything.

Any help on getting round this would be super greatly appreciated

Sounds not really good. Sorry I have no idea at the moment, but it could be that some log-files cause trouble with iTunes Match. I would call Apple's iTunes Support and explain the issue. I am sure that they can reset your iTunes Match account and disconnect all your devices from the service for a fresh start.

I've got a similar problem that has only appeared since ML.

Loaded ML on to MBPR and setup main account with id and match working all fine.

setup new user (with different iTunes/icloud id)

logged back into original account and match has stopped working saying that the machine is associated with another id.

it almost seems to think its a device like an iPad/iphone where only one id can be associated per device completely ignoring the different users.

Am I missing something? is this a ML bug?
