The translation memory data file is corrupt

Another problem has come across for several months. I was observing the problem and trying to find a solution myself. I had exported the "sound" translation memory in a .txt file to import it into a new TM. I did this several times. However, since I'm using Trados Studio 2017 this same TM (even after having imported it into a new one) will corrupt after only some usages. 

I also used the "TM Repair" which seems to be no help at all. 

Sometimes I'm really wondering why I'm using Trados Studio 2017 because everything was fine before.
