    Hey I got a question about the first fix. The one for the crash when the play button is pressed. How do you execute this if you have windows vista?

    hello, i play about 3 or 4 hours and later the game will be freezing and playing like a robot, what should i do?

    Check your computer to make sure you aren’t running out of memory and that your computer isn’t overheating. This game has some memoryleaks I am sure.

    I have reviewed all this, have even uninstalled it and went back to install past 3 or 4 hours sims are getting too slow and time, otherwise the game is normal

    I think I know the answer when the sims just suddenly hang.. I did all this steps and it still not working.. what i did is run up the last saved that I have, place a copy on my folder choose that copy and make it as the one that I’m gonna use.. so far it doesn’t hang anymore 🙂

    Hello, I downloaded S3 Late night and run it on my laptop. Every time I try to play through Launcher it says “Launcher crashes” – I uninstalled and reinstalled the game 5 times till now, EADM also 5 times. I do everything like it’s written. But I found out that the game is not patched. I downloaded from Modthesims one program called The Sims 3 Patch downloader. I run it and when it comes Late night patch, it says $Error. Invalid file somethng” That’s when I try to install patch manually. The program patch downloader says the problematic file is TSLhost.dll. I’m tired of trying to run my game normal.I have CC, but I use Custom Launcher and it installs perfectly my CC. Also I downloaded Twalaan’s mods StoryProgerssion and Master Controller.. I wonder should I try one last time to reinstall all the games and expansions or should I come back to play Sims 2, I’m totally disappointed from those errors. I liked so much Late night… but now it’s teasing me.

    Hello. Im having this sound lag/stuttering and sometimes all sound stops and it comes all at once. It started with the base game so im not blaming Late night but i do get the crashing launcher. i contacted ea and tried everything they suggested and nothing works. I keep replying they are going to get sick of me!!

    I have looked all over the internet for a suitable answer to my problem and came up empty handed… I purchased sims 3 late night and when i came home and installed it everything went smooth untill i went to play it… When you open up the launcher it shows small icons for the sims 3 and the expansion packs… well it wont let me switch to late night. So i pressed play for the hell of it (eventhough it wouldnt switch) and it went through the motions of starting late night, probably because i had the disc for it in! Im completly stumped, my computer meets the requirments and i have the sims 3. If anyone can help me please comment… I feel like my 40 bucks is down the drain…!!
