Termbase cannot be opened due to unsupported version of MultiTerm

Hi all,

I have an sdltb that I used to work with, but it appeared to be incompatible with my MultiTerm all of a sudden. Here is the error message that the tool returns every single time I attempt to open my termbase:

I really struggle to realise what the problem is because I used to work with this file without experiencing any problem.

My current MultiTerm version is SDL MultiTerm 2015 SR2 - 12.2.1629.0

Do you have any idea what this is about?

 

Thank you
