Sorry op, I'm not sure if it's possible to reset your Robosoft program, but you can try reaching out to their official support team and see if they can assist you. Maybe their Twitter or FB pages will have an active link to their support email or contact form.
I don't speak Russian, but I think I get the gist - you're trying to remove the software restrictions and are willing to pay 50$. If you're looking for a legit way, have you tried reaching out to the developer directly? Maybe they can provide a solution or point you in the right direction.
"Hey guys, I've never used Robosoft before, but I've seen a few threads about it being a Russian dev tool. If you're still having issues, you might want to try contacting their official support or looking for alternative solutions instead of paying someone for a 'hack'."
"Dude, no idea about the Robosoft thing, but I think the $50 might be a bit steep for just a refund. Have you tried reaching out to their support team directly? Maybe they can help you out for free."
