Alright. For the 'Feralheart.exe has stopped working' thing- that usually signifies that a file is in a folder it shouldn't be.
For the 'failed to connect to map server' thing- that usually is an issue with internet connection. I'm likely wrong, but, possibly one of the items from the Pawsome pack ended up in an incorrect folder, which is making the whole game crash AND making the map server lose connection. My advice is to just scan through each Feralheart folder and make sure everything is where it should be.
