msieve has stopped breathing in the middle of execution.
I'm working on Windows 8.1 Professional with core i7.
For the given n in the website n=2881039827457895971881627053137530734638790825166127496066674320241571446494762386620442953820735453 it stopped working in the middle giving error as shown in the images. It was working well for the polynomial selection, and for the initial steps of the sieving phase, didn't give any error. But suddenly in the middle this error came out. Please Help.

You can try restarting msieve manually, by copying the last command from the text window with nc2 changed to ncr nc3.
You can try starting factmsieve.py the exactsame way you originally did, which will restart the linear algebra step (the one marked nc2). The factorization may finish normally. For a bigger project, the first option saves time, but in your case this is a smallenough project that restarting the LA step won't cost you much time. If neither of those work, post the log file, which may contain the specific error msieve is coming across.

This is the screenshot of my example folder, and it does not contain 'example.log' file.

Check the one between example.lcf and example.log.T0. Many extensions are hidden by Windows by default.

The log you posted doesn't help us; it only shows the polynomial. If you renamed example.log.T0 into example.log, you didn't post what might help us figure it out.
