Error 4010 on iTunes when i use Match

Hi

I am currently experiencing problems using Match on my iMac. I am using iTunes 12.1.0.50.

Whenever I use the Match button it goes to the page and starts the process but after about a minute it returns the error 4010 and stops. Have looked at many other problems on here and the net but none of the solutions seem to work for me. iTunes Match works fine when I use it from my work laptop.

Thanks in advance for your help.

Nic
