[varonrot]

I install indicator that made damage to all my script.
In order to solve the problem I've removed the software delete the folder 'NinjaTrader 7' and installed again then Restore backup.
I receiving this error "NinjaScripts files can't be restored, since they would corrupt your installation"
The problem is that I cannot open the script and compile because I cannot restore the backup.

Hello varonrot, and thank you for your question.

NinjaTrader backup files are zip files. If you change the name of your file so the .ntbk part becomes .zip, you can open this file with your favorite zip utility. If you can not see the .ntbk part of your file inside (My) Documents\NinjaTrader backup, please use these publicly available instructions to reveal this part of the file name.

Once you have opened up the zip file, the files and folders contained within belong in your (My) Documents\NinjaTrader 7\bin\Custom folder.
