From what I understand, MQ2Mule is a UI for MuleAssist macro. You can copy MuleAssist.mac to your macro folder and it will work fine, though no UI.
MQ2Mule is not open source so it's not something we can provide. We do offer MQ2Bot that does the same thing but doesn't have a UI currently. Xeniaz is in the process of creating a UI for MQ2Bot.
You could try copying the dll over and loading that.
