Interesting, this looks like it can only happen if the chunk loader tries to create a ticket for a world that doesn't exist. Can you reproduce this behavior, and you may wanna talk to ChickenBones about it as it's his ChunkLoader.

Either run a profiler on your game to see whats taking the processing time, or uninstall anything you have that isn't forge. Log files are all nessasary. Forge does NOT kill your FPS. {It actually gives improvements} So, logs/profiler info.

You'll have to look at the indavidual install instructions for those mods. However, just guessing but those sound like jar mods. And we don't support jar mods.

Well, the modding procisure has gotten quite a lot easier this update. Seriously. Run the installer. Put mods in mods folder Run game... Thats it.

Did you edit the jar? If so why? Stop doing it.

I would say he needs to go update his video drivers. As it's failing in the ati drivers.

it doesnt install it into your 1.5.2 jar as the new installer uses the new launcher's format. Also, we dont touch the jar at all anymore. What you should do, is move to the new official Mojang launcher. So: Use new launcher Run official 1.5.2 and 1.6.2 versions once each. To mod 1.5.2: http://www.minecraftforge.net/forum/index.php?topic=9695.0 To mod 1.6.2: Just use the installer. You'll also wanna set the gameDir in the profiles so your mods folder dont conflict.

Redpower doesnt exist for 1.6.2 As for bukkit servers, you need to use MCPC. You Can't install forge on a standard CraftBukkit server.

You're missing the libraries, if you used the installer they should of been downloaded for you. But you can manually place them by copying the libraries folder from your .minecraft folder into your mcp/jars folder.

You installed something else into your jar that you shouldn't of. You need to clean the jars and re-install forge. Don't edit anything in your jar.

Sounds like an issue with Pixelmon not Forge.. go there.

Neither of those mods need to go into the jar

Delete the file from the mods folder!

Minecraft Version: 1.6.2 MutantCreatures{1.3.4} [Mutant Creatures] (Mutant Creatures v1.3.4 mc1.5.2.zip) Unloaded Really?

You have something locking one of the files it's writing to. Reboot your computer and try again.

Use the standard launcher, not Magic Launcher.

Why are you posting here? It'd be best to post over on the Magic Launcher forums as we have no association with them and it's there software you're having issues for.

Have you ran 1.6.2 in the new launcher before installing forge?

It's a log file.. in your .minecraft folder...

Post the FML log from your minecraft folder. And also use the spoiler tag as posts that are several pages long are annoying -.-

How did you install Forge? Did you use the installer? The issue is that it can't find the ClientBrandRetriever class which should be inside the unmodified minecraft.jar. How are you running the game?

Install optifine AFTER Forge.
