Trouble after upgrading JDEOW Adapter

I just upgraded the JDEOW (JDEdwards OneWorld) adapter to a newer version, and suddenly my JDE ports are failing with the message below. 

For some reason, the ports are trying to use the old version of the adapter DLLs.  I’ve tried creating a new JDEOW send port, but no luck.  I’ve also removed and recompiled/deployed the application without any luck.  I also replaced the “old” JDEAccess.jar with the new one without success.

Can anyone tell me where we can fix this?

Thanks!
