Don't panic Huston, no problems, just solutions..
I was hunting through D:\My Games\ getting confused with the steamapps\common, but I can see now where I am supposed to be.. I have changed the folder to C:\Users\ricky\Documents\My Games\GC3Crusade.OLD, however, unfortunately, the game still constantly loading at "Loading Players", I gave it a good hour to try and load but still the same spinning galaxy.
I could try uninstalling and re-installing locally or try another EHD? Maybe that is causing the issue, it's odd that the other games I have installed and downloaded on to the same EHD work fine, including; Sid Meier Civ, Sins of a Solar Empire even Demigod all work no problem and I'm only using 113GB on a 2T drive, the machine is low spec but it has clocked up some good hours with no problems till now.
Any further advice will be greatly appreciated
