I purchased Limewire Pro for 18.88 through Limewire and have the documentation from limewire. My bank shows that it was form limewire. The problem is that I didn't use he prior customer discount link and payed full price again. I wasn't thinking. I used the same login email address as before and that is where, I think, the confusion is coming from. Limewire never updated my old login info.
P.S.
I meant order number not Ref. number. sorry

p.p.s
I had limewire pro a year ago. I got updates and everything fine from Limewire. It just expired. I do check the validity of sites where I make a purchase.
