I added the @Scan.showdialogs=yes you recommended for KODI 18

Sorry, that should have been @Scan.showdialogs=yes (lowercase "s" on "scan") - the options are case sensitive, I may have originally typed that from a tablet which auto-corrected it. I'll update the original post.

Edit: Nope, the original post is correct - it's the forum that has matched @Scan with a forum member called Scan so it displays [at]scan.showdialogs as [at]Scan.showdialogs.

also, sleep gives me a message that it's not recognized

The original post was for Linux - you'll need to use the Windows equivalent of sleep, something like timeout 3 >nul might work.
