Cant upgrade to PRO version

[bournemouthguys]

I tried to upgrade and purchased Limewire PRO but could not install it. When I tried to install it said that another version of Limewire was running even though it was not. I had to cancel the installation. I rebooted and tried entering my email on the Limewire website. I keep getting a message saying that the email is not the one I used to purcahse Limewire via paypal even though it is. I have got my confirmation number and detail of payment being made by paypal. What should I do now as because it wont let me enter my email address used omn the Limewire support website so I cant contact limewire support? Anyone got any advise please?
