Communications Support Forums

I recently purchased a UHF XPR 4550 (AAM27QPH9LA1AN) used from eBay in the hopes of programming it to work on DMR-MARC. Since I use this for Part 97 I have traditionally programmed with CPS 8.0 for 25 kHz support. This radio however came loaded with Firmware Version R01.12.02 and Codeplug Version 13.00.05. As my current CPS was too old to read this radio, I was able to upgrade my CPS to 10.7 in the hopes of loading the codeplug. However, now when I try to read the radio I get an "Error #1057: Region not support" message. Can anyone offer any advise for how to move forward from here? Thanks.
