iTunes purchase issue

Hi,

I have an issue with iTunes on my Windows. I cannot buy any item from the store, it was working earlier but now for about 2 months problem persists. I'm clicking buy, it asks me for a password, then confirmation of buy and nothing happens. With the same apple ID on my ipod touch I can buy things without any problems...

I have contacted support many times, updated Windows (10), updated itunes...

Is there any log file that logs application issues? To be honest I stopped purchasing things because of this issue, this is very frustrating :/

Could you help me with that?

Cheers

Rad
