Due to space limitations I needed to download everything I get to an external Drive (D:) but because the files location is in (D:) and not (C:) the root is different, and some names has changed. Whenever I go looking for C:\ProgramData\Tacview\Data\Database\Default I instead look under D:\Program Files\Tacview\Data and don't see database anywhere leaving me confused. So basically, I can't use any model or terrain data or even see myself when I load up tacview, everything runs fine and I see the ai doing its thing but where is alpha 1-1, I see where the carrier is, but I don't see a carrier just a box labeled "carrier".
I don't know about reproducing this since i don't have enough space to even attempt otherwise but if you can I'd suggest getting an external hardrive and moving try downloading on a new pc or something
