I participated in original muse token sale.... (how do I check my balance?)

[hammyburger]

I participated in original muse token sale.... or peertracks... or whatever it was called. I have the wallet from which I contributed, along with the priv key, etc.  But I have done nothing else with my tokens. Can anybody tell me how I can check my balance to confirm all is cool in the new blockchain? It doesn't appear I can simply look up my wallet id to see my balance.

I don't plan on transacting or anything like that yet, but I want to start learning about how I can participate.

Thanks!
