Currently most common cause of -1 error is lack of any enabled audio device. I will fix it in next release.
Theme problems are normal. Steve shutdown code don't fix everything.
Second (short) try, lost a whole bunch before posting
Audio device is enabled; using Aurora.ini (portable default) I hear music right after starting Aurora Wrapper.
Enabling music and voice ingame doesn't make a difference.
Also "musicdisabled = 1" nor "musicvolume = 90.3" has any effect - same loudness.
Your MSSTDFMT.DLL and MSVBVM60.DLL are exactly the same as I could find (just in case).
Running 3840x2160 side by side with 1920x1080 background overlaps ~50% (eye measured) of the second display. You can handle this i.e. with Alt-Tab. Win-Shift-RigthArrow will place any Aurora-Window far outside - just use drag 'n' drop instead. No problem using Excel side by side with Aurora Portable.
Galactic Map will become hidden after opening System Map. Same for some other windows and Map occasionally and vice versa.
Tested compatibility modes: 95/98/Me end up with "Fatal Error!" while XP/XP SP2/XP SP3/Vista/7/8 end up with reported one.
So far (tested all documented (Ctrl-)F?? and Ctrl-?) it seems only System Information (F9 and Ctrl-A + Open) is affected.
Hope that helps...
