Space Rangers 2 on Windows 7

[Meteoric]

I Love this game, Space Rangers 2: Reboot.
But the worst part of this game was RTS.
Because it was buggy & It can't Save & It was Very Hard to control 1 or more unit = Hard to win.

My Laptop was BenQ S42 + Win7-64bits:
My Laptop & Game crash to Black Screen a lot of time in RTS & many at nearly win point.
+ RTS Can't Save, that mean I must play very hard control RTS Again, Again, And Again.
Please, Fix this error OR at lease add a slot save for RTS game.

Another problem I found is, When play about a hour OR load game many time,
Then the game will start lag more and more. And only way to fix this is Close & Re-Open Game Again.
I think this bug may be come from accumulate unuse data.
And I sure the game programmer can fix this bug.

Anyone have any idea to help my RTS problem, Please tell me.
Thank you very much.
