There was a problem sending the command to the program - Still in X6

Hi to all.

I have the same problem I had with my installation of CorelDRAW X5 in my Windows 7 32bit laptop and is still present in CorelDRAW X6. When I try to open a CorelDRAW file from Windows Explorer, the program loads, and an error message pop up that says, "There was a problem sending the command to the program." and then the file will not open. This only happens opening the cdr file from the windows explorer and not running CorelDRAW. If I open CorelDRAW first and then go to  windows explorer and double clic the file to open it, it has no problem an no error message pops out.

This is a clean installation of CorelDRAW X6, removed X5 completely, cleaned the registry and deleted the Corel folder in program files

Any suggestions?

Thanks in advance...
