ESoftscript licensing problem, but ess had closed this business.

I'm back on this forum after a long time.
I am facing a problem with my paid script.
I bought eSoftscript for my website
after a long time tried to log into my admin panel,
I found your license is not valid.
when i opened the esoftscript forum for hlep.
I saw it had closed the company.
if there is a user of ESS pro, can he help me? What is the solution?
finally I deleted my script from my website.
can any one tell me the solution of ESS pro?
