I bought ProMass for Xcalibur years ago and I need to re-activate my copy/lost my copy/lost my computer/moved computers/etc…

Unfortunately, ProMass 2.x for Xcalibur is no longer supported.  However, you can upgrade from any 2.x version to the current version for a very attractive price if you contact us. You only need a valid CD barcode to verify your original purchase.
