Are you running single player or on a server? It might be the server needs wiping and re-installing, other than that a total uninstall of everything Tekkit Lite from your system and a fresh install is all I can recommend, it sounds like you have a corrupted file in the powersuits mod? It's hard to tell without an error (if it actually generates one that is).
