Tried rowing with only PM5 (v3). In other words, without using either ErgData or RowPro while rowing this little piece. Afterwards tried to upload data from PM5 v3 with C2 Utility but it reported 'no data' on PM5 and returned error code 201-46. Im guessing that it is because this is a PM5 with beta firmware but the version of C2 Utility is expecting non-beta firmware and that causes it to see 'no sessions' in memory.
