Ctrader cannot start

I'm currently using ICMarkets cTrader. This is the second time I'm getting this error. I got one yesterday morning and solved it by uninstalling and reinstalling cTrader. I thought that solved the issue but the error popped out again after being fine for the rest of the day and this morning.

Please advise me because I don't want to be uninstalling and reinstalling every day.

Application cannot be started. Contact the application vendor.
