Limewire ive paid but cant get access

[dnstlh]

Hi
I purchased Limewire pro about 9 months ago and have recently got a new pc. i went to download the software again and went to the already bought pro section , it keeps telling me my email is not a valid email with limewire. i have succesfully done this before when i formatted my last pc and had no problems . It is no longer on my old pc and i still have the same email as registered with paypal this being my payment method to limewire.i cant contact them because i need to enter my email and i get the same response im not a limewire customer. It is supposed to be a one off payment for pro. can anyone help as to why im unable to access pro or on how i can contact limewire

thanks
