not wanting to bug anyone but i have encountered this issue.
I installed RPpre5 IC² 1.90 and railcraft 5.02 and everything works fine, by the way MC1.2.5 ML1.2.5 and MLMP 1.2.5v1 and forge 3.1.2.94 and it all works fine untill I run MC Patcher over it, still no large issue ther, but as soon as I add a texture pack to the folder and click the test button of MCPatcher 2.3.6_01 I get following error log :
mod_ModLoaderMp 1.2.5v1
mod_MinecraftForge 3.1.2.94
mod_IC2 v1.90
