I noticed that you have version 4.5 of advanced machines. This has been updated to 4.6, and it also has the IC2 API bundled. an update or a removal of that api might work, haven't tried myself yet. I will check to see if i see any other possible issues, and update this post if I do.
Edit: Railcraft and forestry also include the API, forestry only partly so. Again, i have not tested anything, just giving you some more places to look for issues.
