cant save helo please

every time i try to save a sample on my mpc it come up with saving and then a line is going through it and it doesnt save. It does when i try to save a program with sample, samples alone and all programs and samples. If anyone could please help that would be great thank you.

what kind of mpc do you have and to understand you better, are you trying to save individual samples?

Sometimes downloading the OS again onto a new disk helps fix strange problems. Try that if all else fails. See if it works.
