pockets restoration – Simply obtained again into bitcoin however theres nearly no manner for me to make use of my bitcoins, please assist!

I just lately obtained again into bitcoin after 3 years and I need entry to my pockets I saved on my HardDisk some time again. It appears the pockets supervisor I used (multibit pockets) is outdated. Nevertheless NO different software program appears to have the ability to learn my pockets so I’m caught utilizing it. I can’t ship bitcoins to anybody as a result of it sends and is pending for days (3 days at this level).

I watched a youtube video that described the way to switch multibit pockets to electrum however that video didn’t assist and the commments part was closed (I think as a result of it simply doesn’t work).

What can I do? I can’t use the rest however an outdated multibit software program however the software program doesn’t ship bitcoins accurately…
Am I simply out the entire cash I invested on this?

P.S. I attempted sending the bitcoins to coinbase as a result of that web site remains to be up however they find yourself being pending for days and coinbase will not be getting again to me.
