trados studio 2024 will not start

 I live in Greece but travel a lot.Two days ago, I landed in Zanzibar.

Since we landed, my TRADOS 2024 would not work at all.

I tried different things such as using VPN, renaming files, repairing the app, uninstalling and re- installing but nothing works.

I only got one message initially  "The is no instance of a key"

I am desperate because I have projects to work on and my clients are not happy about this.

Kind regards
