If you have a phone number for support, I very much fear that you may have purchased a scam "subscription" to Limewire, as Limewire can not be reached by 'phone. Neither does Limewire offer a 7 day trial period.
Go to
www.limewire.com to see the only place to obtain Limewire. The Basic is Free and pro costs US$ 18.88 and is valid for 6 months.
This thread might explain a bit of the Scam site problem.

It would be interesting to know what link you are using to try to obtain pro.
