Delete the "ic2" folder in the TC2 zip

Thanks RichardG, that solved my problem. My only question is what effect will that have on thaumcraft?

No effect, it was using an outdated API.

Quote from Alblaka

This issue is plainly related to which API of IC is loaded last. If mods use the IC² API, they usually contain the API itself, causing them to override each other.
If the last overriding API (last mod loaded with API included) isn't the most updated one, IC² causes a crash because of being forced to work on the outdated API.

I think one could release a fix-mod, which is labelled mod_ZZZ* and solely consists of the Ic2 api and an empty mod-class file.

While I'm not certain about this it seems the API loaded first is the one that overrides everything else, not last. Or should I say prefixing my IC2 file with [0] when everything else started at a minimum of [1] allowed it to work, and if I used [4] to put it at the "end" it had this error. All the same, something like that could be useful.

Hellow,

I'm having a crash, on startup, (not a ID conflit, since I have TC2 installed, (I changed there block IDs, I diden't found the option to change the block IDs on IC2))

I get the exact same thing and I tried what somebody else said like "Delete the ic2 folder" in some other folder and that didn't work. Maybe I'm deleting the wrong thing but I've been trying for a while now and it's getting kind of frustrating... any help would be great!
