@xAnti I would suppose that this time the problem is caused by something different as it was the first time. If it would be the same reason, you could again solve it in the same way. And nothing happens without a reason. So there must have been happened something. Maybe a windows update, an update of the graphics driver, of any other software ( especially anti-virus software) or have you downloaded a new mod or vmod or new other software. Or it also could be corrupted hardware. Or, or, or. It's almost impossible to find it out what causes the problem, without to have access to the computer where it happens. If you can not solve it this time, i would suggest to directly contact the s397 support.
