I love it so much, it's my favorite game of the year, but I am having tons of issues. 
 
First, the Left 4 Dead 2 servers were laggy as hell, everyone knows that.  
 
Second, is that the servers have some weird problem with my router, so whenever I try to play versus or scavenge, it completely shuts down my internet. Not just Xbox Live, but it completely shuts down my router and modem. I fixed that my updating my router firmware.... kind of. It still happens every now and then. 
 
Third, I was playing the other day, when my dad knocks over my 360, and you know what happens. It was scratched so much it doesn't even work. I take it to a local movie store, where they refurbish it for me for $1. The scratch is mostly gone. I'm happy, I take it home, and I notice that a lot of textures are missing. Power boxes, suit cases, tarps, fire hydrants, boxes, soda machines, as well as a lot of other stuff appear as blue and pink pixels. 
 
And fourth. My connection gets one bar no matter what I do when I play versus. It's not the servers anymore, since everyone else seems to get good connections. It is so laggy to the point where it is completely unplayable. That wireless adapter is a $100 piece of shit. The weird thing is, that when I'm in the 360 menu, it shows me getting four out of four bars... 
 
I just can't win when it comes to L4D2. So now I ask, has anyone experienced any of these problems? Or had a game that you loved, that for some reason you just couldn't play properly?

Hey, I've got problems with it too! 
 
I bought it for PC, I played the demo just fine. Got the real game and crashed every time a Witch died.
 
Then the next day, When I went to load up L4D2 it went to the yellow loading screen thing and crashed. Every. Single. Time. 
 
So I can't even start the game!  I played it for a day and now I can't play anymore! I basically donated 45 bucks to Valve and they haven't even fixed this HUGE issue yet.

Good to know. Thanks for the info. 
 
Yeah, same for me. It's really annoying. I never had any problems with L4D1 though, which is weird.

Did you not install the game? HDD issues or something?

" @Zenaxzd: Dude you're brilliant.   The reason I didn't install it was because I have a 20gb HDD. Do you think the texture problem will be gone if I install it? I'm assuming not, but you never know... "

"  @Zenaxzd: Thanks. :D   I'm thinking of upgrading to a 120 soon. If they weren't so freekin expensive. "

" @ADTR_ZERO: Yeah, you were right. I tried installing it, and it wouldn't even install. It gave me an error.  I'm so fucking pissed. I spent all of this money on the game and it doesn't even work right. D:  I'm sad. "
