I need help with mcore3

[Konata36]

So, I've been trying to install mcore3 and the vampire plugin to my tekkit server, and it loads both, but once it tries to load the vampire plugin this happens:

2012-11-10 03:21:11 [sEVERE] Error occurred while enabling vampire v5.0.1 (Is it up to date?)

java.lang.AssertionError

Anybody have any ideas on how I can fix this?

This plugin is for CB 1.2.5-R2.0, you need 1.2.5-R4.0 or above (Anything Above is not always going to work also) except anything using 1.4.2-RX.X.

So, whenever I try the 1.2.5 R4.0 version, it still gives the same error :/
