Okay, first i would like to apologize if an answer is actually out there but i did search but the reason i wouldn't have found the answer is because i'm not sure exactly what to look for, so anyway here it is
i read a lot of guides on model editing and they all started off the same way, opening MyWarcraftStudio and then proceeding to open Common.MPQ, now i did exactly that as shown in this screen shot
and once i opened the .MPQ file nothing came up in the left panel, as shown in this screen shot
i believe there is a fix for this but i just couldn't find it, thank you in advance for helping me
