Why is that hard to import BTS keys in MUSE wallet?

[dritz3r]

I was using web BTS wallet. After exporting private keys I successfully imported that keys in BTS Graphene wallet, BTS was there. But I have no luck with MUSE wallet. Where is the problem? After countless tries now I receiving message that my keys are already imported but I can't claim my coins. Thanks again. I'am begin to feel little desperate. You are talking here about big plans, but even  basics staff are complicated here.
