Are you using Nest 3.11 or Nest 3.13?
Although I've been using RTD for more than two years and am aware of certain issues,
there are times when it gets frustrating, this has started since the new Nest 3.13 has
been introduced. Prior to that everything was hunky dory.
Your issue is very new, so do trial and error to sort out issues.
I find uninstalling and reinstalling Nest, downloading a new copy of RTD and uninstalling and reinstalling Amibroker works at times.
If uninstalling Amibroker,t first backup your database folder. Use Revo uninstaller if you have it, to do a clean uninstall and reinstall Ami. Start Ami create new database in Ami, then go to Menu; Symbol>New; type all the symbols you use with a comma in between two symbols/scrips.
Now you need to transfer your old data to the new database. Close amibroker and navigate to the partition ami is installed in, go to the new database you created , double click the folder, you will see folders '0 to '9' and 'a to 'z'. all data is stored in these folders. Now copy the data from old database to new database, by going to the old database folder you backed up, go to folders alphabet wise. (eg folder 'a' would contain AXISBANK, and all scrips starting with 'a'; folder 'b' would contain BANKNIFTY and so on) copy the scrip from the old database folders to their respective folders alphabet wise in the new database, doing it this way is avoiding bugs/errors that have crept in. This is a quick copy paste method of transferring data between two databases and has worked for me. when all is complete you start Ami, you have all your old data back in a new copy of Ami.
