How can I open my 2011/2014 termbases in Multiterm 2015????

Hello,

when I try to open some of my old termbases created in MT 2011 or 2014, I get the following message:

"There was a problem opening the termbase at C:\(PATH WITHOUT SPECIAL CHARACTERS LIKE ";" OR "&"). Check that this is a valid termbase and that you have permission to access it."

Does anybody know, what this message means? I found some KB article regarding "special characters", but there are NO special characters in the file name or in the path. I have installed Visual C++ SP1 too.

My computer runs on Win 7 SP1, MS Visual C++ SP1 is installed.

Thanks for an idea how to remove this @!*GRRR message and to work with old termbases.
