Please close this issue, it looks like you solved it from your forum post.

Exchanging Forge Multipart v1.1.2.331 with v1.2.0.336, which extrautilities was missing, caused another crash, but replacing it with 1.2.0.345 did the job

The issue seems to be related to ExtraUtilities and i was able to fix it by manualy exchanging Forge Multipart with version 1.2.0.345.
