No acces to blockmarket. Private keys available. How to retrieve SYS?

Hello,

On my old macbook I had Blockmarket 2.0 installed. I tried to upgrade it to 3.0. Unfortunately things didn’t work out as supposed to. I wasn’t able to access my wallet and alias and see my syscoins. At the moment I do not have any blockmarket application installed on my new macbook.

I do have my address, public key, password, private key (also for alias). Is there a possibility to retrieve my “lost” syscoins?

Thank you very much in advance.

Regards, Laurens

As long as you have your private key just download QT https://github.com/syscoin/syscoin/releases/tag/v4.1.3
Let it sync then go to the Window-console and type importprivkey yourkey
