MultiTrans not responding after clicking on "Start Session"

Everytime I click on "Start Session" to use MultiTrans, the software stops responding and freezes. It can take up to 10 minutes before the software start responding again. It can take about 45 minutes to open the software entirely and have access to my TextBase and TermBase.

I use MultiTrans v.6.1.19128.3 

We are a team of translators who are all using MultiTrans at work and we are all using the same version. I'm the only one with this issue. It's not a problem with my work computer either because I changed my laptop recently and I'm still having the same issue.  

Thank you!
