I just updated LP to version 205, and my pipes stopped working, as if they don't have power. I tried several different power setups, and none of them worked.

Did you make sure, that your LP pipes are on the side of the power junction?
Could you post screenshots.

And as a side note, your TE version is outdated resulting in
2014-05-20 07:44:17 [SEVERE] [LogisticsPipes|Main] Disabled ThermalExpansionProxy for Mod: ThermalExpansion. Cause was an Exception

I fixed it. Turns out there was some conflict between an IC2 MV transformer and a TE RF conduit that was mucking up my power grid. XD Crashed my game a few times before I figured it out.

And thanks for the heads up, I got TE all updated.
