Can't fix this issue no matter how hard I try. I own Half-Life on steam and have steam open when I try and open the .bat file. I've tried restarting steam, restarting my pc, uninstalling and reinstalling Half-Life. I've tried the 2005 package instead to see if that made a difference but just received a "SteamAPI_Init_Internal failed" error. I'm completely stumped, if anyone can offer some suggestions to help it would be much appreciated.
