Just needed to re-emphasize this: there are only two options for that crank. Check to see what you have, it's either one or the other. That the wrong (i.e. triple) version might have been installed is is one of ONLY TWO possible solutions to this problem, using this crank.
One minor nit though: the V1 triple is 118.5 mm. If you order a 118mm bb, it will be V2 (BTDT) (and I think V2 has quite a bit more than just the two options available in V1).

Are you the crankset spline pattern is aligned and fully engaged with the bottom bracket splines? If not this would explain the chainline problem.

Seriously. Shoota - this is very simple. There are two things you need to check, in this order. If you have BB tools (which cost about $40 in total), you can do all of this in 15 minutes.
Pull the crank and when you reassemble, carefully make sure the splines are fully engaged. I have mis-assembled cranks and been fooled by this. Usually you can tell immediately because the arms don't align properly, but it's not beyond imagination that they might be close enough to not be noticable, and tight enough to feel solidly engaged even though they aren't.
While you're at it, remove the bottom bracket and determine which version it is. It will be printed on it. It is on both Octalink V1 BB's I have and the 118mm Octalink V2 I mistakenly bought earlier this spring.
Again, this is simple, just do these two things and be done with it. If it's engaged AND you have the double (not triple) bottom bracket, there's nothing else you can do except get a different crank. There are no other options for bottom brackets that work with that crank.
