Cubas LE8, Record function quit

I recorded a number of tracks just fine. But when I attempted to record the last
track Cubase quit allowing the record function to accept my vocal recording. I checked that the red record button was lit, and it was. I checked the microphone to make sure it was working, and it is. I also tried to create a new file but the Cubase “save as” function doesn’t contain the function to create a new. I’ve done the “save as” function to create a new file trick in LE4. It corrected a lot of crashed files for me.
I am stuck. Anyone got any ideas?
Thanks.

There are Track count limits between different editions. Here is what they are now.No idea if they differ in Cubase 8.
