well that fixed it,thank you very much :)

well I'm sorry for not posting this in the right place,I thought it was a problem not a bug,and I'm running Windows 7 Pro.

well I looked around the forums for a while and didn't see a problem like this so I load the launcher and then I start Tekkit and it goes to the Mojang screen and then instead of loading it comes up with this message java.lang.IllegalArgumentException: Slot 249 is already occupied by ic2.common.BlockTex@758d74b when adding ic2.common.BlockTex@599e80b1 at oe.<init>(Block.java:176) at oe.<init>(Block.java:204) at ic2.platform.BlockCommon.<init>(BlockCommon.java:12) at ic2.common.BlockTex.<init>(BlockTex.java:30) at mod_IC2.initialize(mod_IC2.java:201) at ic2.platform.Ic2.load(Ic2.java:65) at ModLoader.init(ModLoader.java:824) at ModLoader.AddAllRenderers(ModLoader.java:189) at afq.<init>(afq.java:80) at afq.<clinit>(afq.java:9) at net.minecraft.client.Minecraft.a(Minecraft.java:316) at net.minecraft.client.Minecraft.run(Minecraft.java:624) at java.lang.Thread.run(Unknown Source) --- END ERROR REPORT d345cad7 ----------
