A probelm with multiterm of Studio

Dear Mr/Mrs, My windows was corrupted and then I installed a new version. Then I reinstall all our beloved tools among them was Studio 2015. I am using an original version with license ( not a crack one). Yet since this new installation, I cannot open any multiterm and have the following error message. Do anybody know how to solve it.

The error message says: was a problem opening the termbase at (the path of the termbase). Check that this is a valid termbase and that you have permission to access it?

However, I am sure that the termbase is correct and I opened it many time before changing my Windows.

Can any body help?
