Truecrypt kernel module format?

[ZakaqerE]

insmod: error inserting '/usr/share/truecrypt/kernel/truecrypt-2.6.17.ko': -1 Invalid module format
FATAL: Error inserting truecrypt (/lib/modules/2.6.17-9mdv/extra/truecrypt.ko): Invalid module format
truecrypt: Failed to load TrueCrypt kernel module

I downloaded the truecrypt source. But I get this error. What format(s) does it have to be in? What is a module format?

edit:
woohoo for

modprobe -f truecrypt

That and I had to change some of the source code.

But since I had to force it, it makes me wonder whether it's actually encrypting anything?? Anyways, problem solved.
Err... SOrry about that, I meant to edit that, not double post

Thanks for the "modprobe -f" tip. I'm not sure how much to trust it, but it works!
