(1.4.2) Black screen on launch with 349/350

[scythemonkey]

Minecraft does not start succesfully.  Using magic launcher 1.0.0, with all mods except forge disabled.

 

Any ideas?

I too am using magic launcher 1.0.0 for minecraft 1.4.2 I loaded up an earlier version of forge and everything seemed to work except for ID resolver and Auto Switch. After reading some posts there was information that the auto switch bug was fixed in the latest. So I downloaded, started with a fresh brand new .jar file. I loaded up Magic Launcher and Forge Universal 350 (or any before it) and got the error:

 

*** MagicMinecraftLauncher 1.0.0 ***

Any ideas on how to fix? Thanks!

Try using MultiMC.

You're trying to install Forge for 1.4.2 on a 1.3.2 jar.

Thanks keepcalm!  That did the trick.  Using MultiMC made everything work perfectly, and frankly I now prefer it over magiclauncher.

 

Also, in case anyone else stumbles across this I fixed the issue of invisible buildcraft pipes by removing the ropes+ mod.

I had told magiclauncher to fetch the 1.4.2 jar, and the log I posted above seemed to match that, but given that I was able to get everything to work by switching to MultiMC, I'll grant that maybe something in the magiclauncher setup didn't properly switch to 1.4.2.  Anyway, for anyone else who hits this problem the easiest solution is starting fresh with MultiMC... which lets you manage coremods and can download forge direct, so is better imho anyway.

 

Thanks for taking a look!
