Preparing to Launch Garry's Mod...

…the window closes, and abso-fucking-lutely nothing happens. The same thing is happening to other Valve games such as Team Fortress 2, CS:S, HL2:DM, etc. What really ticks me off is that no one else seems to be having this problem so it can’t be an update Valve made or anything. I’ve tried verifying the integrity of the game caches’, defragmenting them, deleting and reinstalling, deleting and reinstalling STEAM, updating my video drivers, and restarting the computer. Please somebody tell me I’m not the only one experiencing this bullshit right now.

Actually, after not playing GMod for a few months now, I’ve been having what i believe to be the exact problem you’re having.

Have you tried all the standard fixes? (cleaning gmod, redownloading games, reinstalling steam)

If you read my post, you’ll know that I did all that.

This has been happening to a few people now. I hope it gets fixed soon.

Do you by any chance have BitDefender?

Yes, actually I got it last week!

Breakthrough?

I just tried uninstalling it to no avail. I’ve also done a deep scan for malware and virus and I deleted some infected registry files. Sadly that didn’t work either.

If I’m not wrong then It will be fixed in the next update/patch.

[editline]31st July 2011[/editline]

Just hang in there

Hmm, I uninstalled BitDefender and it worked for me.

Good luck to you.

I am happy for you, but that also blows. Why the fuck isn’t this working for me?

I just found the problem. Holy fuck.

Turns out the culprit was goddamn Quicktime. QUICKTIME of all fucking applications! It appeared it had some corruption going on. I noticed it sometimes opened a window saying it needed repairing, but I just kept ignoring it, seeing as how I thought it had NOTHING to do with Steam or its games. Boy was I fucking wrong.

I found out that Quicktime was the culprit by use of the Windows 7 Event Finder. I noticed when hl2.exe opened up in Steam, something else opened up just before it disappeared: Windows Problem Reporter, or whatever. It was similar to that. Anyway, I tried looking this weird program up on the internet and it was linked to Event Finder. Event Finder was able to record that opening hl2.exe ALSO opened up a Quicktime exe. They were conflicting. Destroying every trace of Quicktime from my computer solved this problem.

If you have Quicktime, and it’s giving you error messages once so often, DO SOMETHING ABOUT IT! That is all.

Oh my god. Don’t use cliffhanger thread titles. Why doesn’t anyone realise?
