Uninstalled SODE 1.4.2 and also installed/uninstalled SODE 1.3.0 since I didn't find an entry for that one as mentioned above just to make sure my system would be clean from all previous versions.
I then installed GSX and this time everything went just fine
Thanks to both of you guys!!
...and for you Umberto, would P3Dv4 by any chance mean we might get PAX soon
? That alone would actually be a reason for me to shell out another $199 for P3Dv4 because I've been missing those PAX since the first day I started simming back in the FS98 days.
Also I hope it didn't fall off your todo list to customize the boarding/deboarding sounds so they match the time of day in the sim with phrases such as "Good morning" and "Good evening" depending on what time it is.
