Sunlite crashing

[Cirkus]

Hi!

I am using Sunlite suite 1 software with Suite 2-EC controller. I also use APC40 and Iiyama touch screen.
The problem is, that recently, the software started crashing. On some nights, everything works fine, on other nights, it keeps crashing and I don't know what the problem could be. Is is some sort of a software bug, is this the problem with the controller or maybe the computer.
I am running Windows 7 (32bit) on "AMD Athlon II X2 250 processor 3GHz" with 2GB of RAM.

I attached a photo of the pop-up window that shows up when the software crashes.

I hope someone can help, because it's really annoying when the lights crash during the night, especially when I go to the toilet or for a smoke.

Best regards,
Jan
