This has happened twice now, I get this message

There has been a critical error

and then I can't open my MT4 anymore. What is going on ???
Is there some bugs with the system ???
I don't seem to have any problems with other software installed.
I highly appreciate any help as I would like to be able to use MT4.
Cheers and happy easter to all
