Customers that purchased Rumpus since January 1, 2006 receive a free upgrade to Rumpus 5.3 for OS X. For those that purchased Rumpus prior to that date, a paid upgrade is available.

Select the appropriate serial number option in the pop-up menu below and click "Compute Upgrade" for full details, upgrade instructions, and ordering information.

Your upgrade path can most easily be determined using your Rumpus serial number. All serial numbers begin either "RP-" (Rumpus Standard), "RR-" (Rumpus Pro), "MP-" (MaxumPack) or "MM-" (MaxumPack Pro). Your serial number is printed on the registration card included in your Rumpus box, or in the e-mail message you received for electronic delivery of your original package.
