Sorry for the late response, but this is the case:
I have an ‘old’ cryptap.us wallet and have all the (secret) information about this wallet. When I enter
https://jswallet.github.io/#[myprivatekeyfromthiswallet] I get a screen in a myriadcoin jswallet with a new myriadcoinadres and don’t know how to proceed. Can you please explain in steps what I have to do from there so I get control over the XMR-coins in my (old) wallet?
