OK, so basically I'm constantly receiving the E00000046 error, and the reason seemingly changed from the first time I got it. There was a file it couldn't find in EXE2, and following what some people said worked for them, I restarted my PC. Now it seems to have no reason and turns out this error log.
10:21:11.163 --> [i]:Prepare Crossfire Start
10:21:11.164 --> [x]:Error Copy [E00000046]
Additionally, this shows up on start-up and the launcher shows a bar eternally stuck at 0% that only goes up to 100% when I select either SP or MP. This didn't occur the first time I had this issue before I restarted my PC.
10:19:59.047 --> [w]:2. Problem opening save file update.dat for download: Access is denied.
No idea what to do here, so any help would be much appreciated. Crossfire installed perfectly fine, it's just it won't work when I try to boot up from the launcher.
