Printer suddenly stops printing

Question

I have CS 5 on a Mac Mavericks version OSX 10.9 and suddenly CS5 will not print, I get an error message  which reads" There was an error opening your printer, printing functions will not be available until you have selected a printer and reopened any documents", I can print from Microsoft applications and from iPhoto and Aperture. Epson suggest it must be an Adobe problem as the R2880 will print from other applications. It has been suggested that I reset CS5 to original but I cannot where to do that, any help please

Answer 1

This was partly helpful thank you, I have updated manually and all updates have gone in and I can now get my RAW files to open,
BUT
Despite removing printer , downloading drivers again and then resetting printers still CS5 does not give me the option to print, I also have an Epson SX 200 which does not appear as an optional printer when I give the print command,
I seem to be between a rock and a hard place here, Adobe seem to think it is an Epson fault and Epson say it is definitely Adobe fault,
I have over £1000 value of CS5 and an Epson R2880 printer and cannot get a print from it.
I am loathed to take up Adobe offer of paying for CS6 and Lightroom on a monthly basis then find I cannot print on that either,
Perhaps I will have to go back to Aperture, which I do not want to, I can print ok from that, which again points to an Adobe problem,
