When I run two or more cores on the same machine why do I get this error Exception in thread 0: @ fah\net\Socket.cpp:137:<unknown> 0: Could not bind socket to 127.0.0.1:52753: No error?
This is a non-fatal error that can be safely ignored. The core tries to bind the port 52753 and only one core can do so at one time. The core provides a server that is used by some visualization tools. This may be removed in the future.
Looks like you have a few protomol cores going and is normal.
