Payflow Pro Payment Module for Virtuemart

Back in 2000, the gateway was called Cybercash. A few years later Cybercash was bought by Verisign, and after that Verisign was bought by Paypal. All the while, we, as merchants never had to make any changes as the compatibility was preserved. Now, if you login to your [login to view URL] it's going to say you are using the Payflow Pro gateway. So you think, "Oh, well VM has Payflow Pro gateway listed as supported," then you select it and finds out it doesn't work. I went through this a few months ago. I was told by some guru that we're not using a "true" payflow pro gateway, that we're still on the "old merchant key method" and that it could not be done unless someone were to write a payment module for Virtuemart which used this "old method" My current shopping cart, PDG Cart 2003 uses this "old method" I need someone to write a payment module for Virtuemart that will connect it to the gateway using the "old cybercash merchant key method" Hope someone out there is knowledgeable on this one!
