Hi looking for step by step help.
I have been buying Bitcoin without issue. Wanted dash and to save to a trezor. Downloaded electrum dash wallet. For some reason it is a watch only wallet. It will not connect. Being in a hurry to buy dash I sent 17 dash to a wallet address generated from this offline watch only wallet. Now my dash is stuck and I cannot get to it. I have tried everything to get my wallet to connect without luck. I thought the problem was with a antivirus not allowing it to connect I believe I have disabled them. Still no luck.
I'm on windows 10 64 bit. I have downloaded both electrum core 64 bit and electrum dash 2.6.4 I have norton antivirus.

I have the receive address, transaction number, master key.

Can someone please help me recover this dash?
