Some back ground: I guess its an historic thing, pre 2003 all battlesets had there own in built database so it was effectively selected from within the game when you selected which battleset you were going to play, and then from there you could select scenarios. Since 2003 the option (normal arrangement for 'new' battlesets) is that the database is external and as it can't be selected once the game starts you need to know before starting the GE which database you are going to want. The databases tend to relate to time periods so that's not so bad. So most of the xxx2003 battlesets and Westpac are like that, Malacca being an exception as it has the HCDB2 database embedded in it. A scenario's required database will be listed in it's HarpGamer download page plus if you open the scenario file with a text editor and look at the first few lines of gobblygook you'll see some plain text including the database name, eg HCDB170909, that will be the database the scenario needs. (You don't need to do that if the scenario is from one of the pre 2003 legacy battlesets) Loading a scenario that requires a different database to the one loaded into the GE gives an error message similar to your "GetMemAnnexA Error" but that doesn't mean for certain that's what's happened to you, but it's what brought this to my mind. By default the GE loads the database from the commondb.res file in the main hc folder but a different database can be loaded by using a modified command line (eg by using HClauncher or SELauncher respectively for GE and SE, but also by other means more fiddly). Before HCLauncher the two common methods were to rename the database file needed as commondb.res and to swap it for the one in the root folder or to execute the GE (or SE) via a shortcut and manually write into the execute line the flag <-d ?> followed by the full pathname to the database file, Tony's GELauncher was an obvious godsend. If all was working fine for you using the last beta and you were starting GE and SE straight from the respective executable in the hc folder (or from the default game menu) then I think you must have only been playing custom scenarios for the default (HCDB) database or legacy battlesets?
