download of pro

I purchased the pro quite awhile ago and I love it. But now I have a big problem. I had to reformat my hard drive and lost it all. I am not sure how to re install the the pro with out paying. If I do have to pay, I have no problem with that. But when I purchased it I was able to pay with a check and as I see now you can't pay with a check anymore. Any help would be greatly appreciated. Or at least a phone call where I could call.

Thanks so much,
