Hi Doncorti ,
welcome to the forum .
as for your problem -l If nothing changed after rebooting the computer and login again, still having the same problem and since we do not know what exactly caused the problem my advice would be to reinstall the ACHAT.
I do not know which version of the Achat you use but still both of them are equally stable.
There is no big special hardware requirements so I doubt that the Achat caused a problem.
As for the new version most of the computers will run more quickly - especially as your computer is new , you can download it here:

http://download2.funnyadultgamesplay.com/AChat_highdetail_setup.exeIf you have a new computer with new graphics should work just fine
I do not know whether this is an appropriate solution for you but in my opinion it is faster ,
such a sky blue screen with nothing visible - could occur due to various things.
I hope this was helpful for you.
