CorelDRAW 2018 Files won't open, save or export.

Hello there

The problem i have is with an original version of CorelDRAW 2018.

Suddenly last week the program just stopped exporting files.

Now when i open CorelDRAW 2018 i can only open one file before all options to open, save, export and import won't work.

Everything worked fine the whole day then it started happening when i was unable to safe my files.

Note all the options are there and are not greyed out like all the videos i have seen.

Please help.
