I was using MultiBit HD and it was working fine till somehow my kaspers key start to delete it. Then i installed Bitcoin Core without knowing anything about it. and it started to downloading bitcoin blockchain but before it finish i created a payment receive address and put it in my bitpay account. And they sent the payment
I stop downloading bitcoin blockchain because its really big. Is there any chance i can get my bitcoins in another wallet? I have the privet keys from Bitcoin Core
