I just purchased the Challenger Prime gaming keyboard about an hour ago at a local store. I downloaded the software off the site, and I launched it and the installer came out. however, after going into the installer option after entering setup.exe, it says "String_ER_Create_Reg was not found in the string table", then "ER_Create_Reg". I noticed a couple of other people also have the same problem, so I hope I will get a response as soon as possible with a solution!
