All tickers in TWS are lost

All of a sudden, all tickers saved in TWS are gone this morning.

I have made many tabs (each for a sector) and many stocks in each tab.
The tabs are still there but all tickers are fucking gone.

How can I recover the tickers? Which file in Jts can I see the tickers?

 

You can retrieve the recent old Thu, Wed, Tue ... files.

I think it is in your C or D drive

 

did it and is fine now. by that settings recovery thing
