Was running Forge for MC 1.6.2. Upgraded to 1.6.4, then ran the latest installer today. Seemed to work ok, but MC crashes with the following report.

 

Any ideas?

 

Thanks!

... you expect rei's mods to work for 1.6.4 already?

 

Is this your helpful way of telling me that the mod is causing the problem?

 

If so, thanks. If not, then, you go girl!

Yes it's the mod, here is a helpful tip when reading the log files:

java.lang.NoClassDefFoundError: nm
   at mod_ReiMinimap.getVersion(mod_ReiMinimap.java:15)

The first line is the error, you'll learn a lot of the common errors if you just start reading.

The line immediatly under it, *typically* tells you what mod is responsible.

In this case it's pretty obvious: 'mod_ReiMinimap'

 

 

There can be things like 'net.minecraftforge' or 'com.forestry' or things like that...

If you actually READ your errors, it because rather easy to do basic trouble shooting yourself.

Thank you oh so much Mr. Sarcastic.

 

Your post was VERY helpful until the last line. Then you became a schmuck. Obviously, as a new person here (hence the "I am new." tag under my name), it is conceivable that the error message might have been a little overwhelming for me to comprehend. As I usually find Minecraft players to be helpful to each other, I figured I'd give it a shot here. Too bad you are the exception. Your information was very helpful and will allow me to not make such a mistake in the future. The snarky tone just isn't necessary and demotes you from a helpful fellow Minecraft player to a dweeb.

 

Have a nice day!

I was actually being genuinely helpful,. but your rant gave me the urge to ban you so, enjoy your ban and enjoy playing minecraft. Try not to be a cunt next time you work with people who are helping you.
