When starting this new version of Half-Life 2, I can't start Episode 1 or 2. I got my copy of HL2 quite some time ago (maybe from a disc), and had Lost Coast somehow. Even though I got this episode with no problem, the episodes won't start at all. It looks like they're loading for a split second, then bump me back to the menu for the episode.
I've tried:
Uninstalling the game and reinstalling.
Deleting all old HL2 files.
Clearing download cache.
I'm just not sure how to get these games running.
Edit (FIXED): Okay, I got this issue resolved. What you all need to do if you're having this issue is to put in a support ticket. Make sure to get screenshots of any crash messages (I used Greenshot for stuff like this, since it's a Windows error message on my end), and add the crash error as an attachment. Be very clear that you purchased Half-Life 2, but did not purchase Episodes 1 and/or 2. This is basically a licensing issue. They will give you a link to add the licenses for the missing games. This will trigger a download, and you should be able to play after that.
