Can not start SGP. Help, please

Good evening,

I’ve been imaging with no issues. But a few minutes ago the PC stopped suddenly and SGP don’t want to start again. Never before happened this.

An image of the issue:

Any help will be more than welcome because I’m just starting a moonless night session :_)

Thanks in advance.

I uninstalled and installed an older version and it works. But then I cannot read the sequences… they are created with the latest beta version. The one that crushed.

Any shortcut to save today’s session?
