actually i reinstalled my industrial craft and updated it then it stated working again. but my if i open my redstone chest then my game saves and quits. you probably can't help me there but if you can i'd like that. thanks.
There are some items in that chest with items that have invalid ID's for your installation. Probably, reinstalling IC changed some block or item ID's, and one of those old blocks/items is in that chest. Did you tinker with the IndustrialCraft config file before or after reinstalling it? Do you have any other mods, like BuildCraft?
