Program fails to load

question for all you experienced do’ers.

sometimes when I load a program on the monitor screen I do not get the time to finish nor the lines in the program so I trash it and reload it and viola estimated time, number of lines in the program, etc. is something wrong with my machine?

I have had the same thing happen to me. I have my controller hard wired so it is not related to wifi, but it did not seem to me to be related to the size of the file. Not sure if something else in the code causes the problem.
Like you I have always had the file simulation and time estimation work the second time I load the program.
