Predator DNC is saving the uploaded (CNC to PC) program in multiple files. The first one is saved with the correct name, but does not have the entire program. The rest of the program is saved in the DNCX naming, e.g. 123.nc DNC0.nc DNC1.nc, when it should be all one file. Manual Receive from CNC works fine. 

The problem is the Remote Request Timeout in the Remote Request Link is too low. Increasing this value will allow for delays with hardware drivers, networking, and/or older machines. The default is "2000" milliseconds and should work fine. If you need to increase, try "5000" milliseconds.
