Solution

You don't have enough RAM to run it. In your run.bat, search for the value "-Xmx800M" and change it to "-Xmx512M". This should resolve your issues.

You just have to right click

You just have to right click on run.bat and press edit, then do ctrl+f and type xmx.

I tried this solution and it didn't work, you can view my error message from this photo: http://sphotos.ak.fbcdn.net/hphotos-ak-ash2/hs347.ash2/62724_1506005182420_1603008768_1220207_5341831_n.jpg

Edit: I found out that the problem is my minecraft.jar file. It's in the /lib folder but it doesn't seem to be the right version. I've tried to download it from the URL given in the guide but I get a 404 error when I paste it in my browser.

I had the same problem

one simple solution is to delete your old World of Minecraft client, download it again, and also re-download the mincraft.jar, worked for me

Update broke it :/

I logged into the client all of 5 minutes ago and it auto-updated.

Tried to run it and BAM! Error.

I tried deleting minecraft.jar and reinstalling. I'm thinking I should just redownload the whole thing. Suggestions?
