Unable to open any documents in Professional 8

I have not been able to open any documents at all for 2 days. If I check the Home Page in the program they appear there, but they will just not open. This is used for work and I need some of the documents urgently. I have not altered anything and it was working fine two days ago.

I am having the same issue too

anche io stesso problema, ho addirittura disinstallato e reinstallato ma non me lo permette
