itunes match wont connect

Does anyone have the following problem? if so, does anyone know a solution for it? :

I purchased iTunes match from itunes on my mac and then when i click on iTunes match on iTunes it says the following message:

We could not connect your iTunes store request
The network connection was lost

There was an error in the iTunes Store. Please try again later

Now... I thought it would be my internet connection, however it does this every time and i have tripple checked everything and i 100% have internet with no problems, i can acces the itunes store, youtube, download films, etc, etc which i have done at the same time to ensure i was fully connected to the internet..
