MT 2015 and Studio 2015 cannot open sdltb files

Question

Multiterm and Studio 2015 no longer open sdltb files from clients. They open the sample file and older mdb files, but not the sdltb file I need to open. I tried uninstalling and reinstalling, but the situation remains the same. What can I do? The error message mentions verifying that it's valid and that I have permission.

Thank you for your response. I installed the correct versions. Interestingly, I can open the sample sdltb file, but none from the client. I can also open mdb files. The error message asks to verify if the file is a valid termbase and if I have the required permission to access it. This happens for all termbases from the client. 
 I looked a little more into it. When I could open the client's termbase but was getting message errors, the index language was marked as "not specified" with no way to change it. Could it be their termbases that are at fault and not the software?

Before investigating the cause of this issue, please check that your MultiTerm and Studio are the same version. If you installed SR1.1 for Studio, you also need to install it for MultiTerm, otherwise you get an incompatibility between the two programs, which may lead to this kind of problem.
