If you backed up your .htaccess files using BPS Backup & Restore then you can restore your old .htaccess file using the Restore feature. Or if you did not make a backup of your .htaccess file then you can restore it using your web host control panel file manager and restore an older root .htaccess file.
By default I do not believe that DAP comes with any .htaccess code. If DAP does come with .htaccess code then you should be able to deactivate and activate DAP and it should add any .htaccess code that it uses (if it does use .htaccess code) to your root .htaccess file.
Or you would go to DAP settings and resave your DAP .htaccess settings if DAP comes with any .htaccess code, which I do not believe that DAP has by default.
