Coreldraw X8 crashes when exporting anything.

Hello. Coreldraw X8 crashes everytime I try to export anthing, vector images, text, photos, anything. I select the thing, hit "export" and that's all, I get the message: "Coreldraw stop working". Then it says "windows is trying to find a solution", and then "Your program stop working. Windows is going to close it". I could export yesterday, no problem, and I haven't installed any programs, or updated windows, nothing. Tried using the Corel install program and choosed "Repair", and nothing. Please, some help. This is a very serious problem in the Corel software.
