crash uccnc

[kunte]

I have uccnc software 1.2111 Firmware 3.0190 API ver.2.1790 and UC100 interface. Many times it happens to me that my program freezes if the software is turned on overnight or during the day and nothing works. It also happens that the program stops working when I load a longer g code (approx. 13 hours of work, 24Mb). Maybe where is the error that caused the program to crash? I have win7 64bit.
