Minecraft works but magic launcher only logs into black screen

Question

I have changed laptops and to savemy worlds I moved over my appdata minecraft  folder after installing minecraft 1.5.2 and magic launcher 1.1.4 on the new laptop.

 

Magic launcher worked on the new laptop with a new world  before I copied over the appdata.  Now minecraft.exe works and opens my old worlds but magic launcher opens to mojang screen  and then a black screen.

 

Any sugestions welcome.

It might be any mods you have on it.

For example: I have the same problem, but it only started when i downloaded the Aether 2 mod onto it.

Search through your mods to see if any of them are causing the problems.
