Object Editor - what the hell!? It just won't work

[TheManFromMars]

Hey

EDIT (Read thsi new update problem first)
Ignore my EDIT at the end of this and the passage below! The problem is back to being for no reason at all:

"Unable to burn EPB! Please ensure:
1) You have the latest burnerimp.exe executable
2) no-one else has a target file already checked out"

This happens when I try to load an epb in the Object Editor. I have the corresponding .SGM file in there with the epb in the correct mod directory I think. I've checked it a lot of times. I also have placed the _default.burn file in just about every directory that anyone has suggested from looking at other threads online. However none of them have fixed anything. Any ideas or help please?

Thanks in advance

EDIT: I'm doing this for DC though i'm going to try and import SS models soon, this because I don't know how to get the OE working SS, i'm having more probs with that tahn the DC. Currently i'm modding a space marine though so it hsould be fine. But its not.
