Hi Tish,
Ok, to start with its not uncommon for the Metis to encounter that invalid error on entry.. Mine does it often, I am not aware of the cause or the fix, but you can just click ok, ok, ok .. and all is fine.
Now metis along with lots of MX Control programs dont like the WCS default port of '3'.. make sure in your WCS config.ini file you change this and use a number higher then 1024 to ensure that the bots and such will like the room ok. Keeping the same port number for all hosts is ok and I recommend it however, the room number is also made up of the hosts IP number so its impossible to swith hosts and not change names.
When running a bot in a color server its very important to use what is called bot mode. This can be achieved by typing /bot into the Metis screen. When looking at the Chat channel you should see number codes, not colors. You can also admin your bot, giving it a 'b' access in WCS to ensure its not going to get confused reading color codes and not function correctly.
Funny you should ask about the shareguard, Ghost is been working on that and should have it done shortly for you.
I hope this helps you some. Let me know if you have any other questions regarding the wcs or bots..
