Hello, the data file "Program.SQF" of SatPC32 v.12.8b includes the program names DataBackup and TimeSync. The previous versions of Program.SQF did not (by default). If you save your previous data with DataBackup and restore it after the installation of 12.8b the program will replace the new Program.SQF with the previous one without the new program names. To fix that add the program names DataBackup and/or TimeSync (without extensions) manually to the file Program.SQF. The file can be opened and edited from the SatPC32 menu "?", "Auxiliary files", "Program.SQF". It contains also the necessary hints. 73s, Erich, DK1TB
