client keeps crashing after placing portal on rp2 tunnel bore

[DemonSteve]

Hello,

I don't know whether this is the right section to post this, but my ftb keeps crashing everytime I start it up.
The first crash happened when I activated a portal spawner on my tunnel bore (built with redpower frames)
This made the client crash, and now every time I start it back up it crashes before even having rendered anything.
The crash report that is included is as follows:

I hope you can help me, since I already was pretty much endgame and I wouldn't like giving up my entire world :/

 

[DemonSteve]

EDIT:

I tried different solutions:
-deleting the level.dat file
-editing my player position
-deleting the chunk loaders on my tunnel bore with MCEdit (with my player 2000 blocks away from it), so the chunk shouldn't even load
-disabling redpower
-deleting my entire tunnel bore
-disable the portal mod
-I redownloaded my modpack

none of these helped.. any suggestions?

 

[DemonSteve]

For anyone with a similar problem:

I managed to fix it by copying nearly everything form my corrupt world and paste it in a back up I made a couple of month ago.
Everything worked, exept for the tunnelbore: MCEdit rotated some panels and covers on the support frames.

Thx for your help
