Hi there!

I've managed to setup AEL on my Pi 3 with LibreELEC through GameStarter. Everything works great, but I've noticed that if I use "AEL Offline" as my "Metadata scraper" my NES ROM collection doesn't show any metadata for my games, so... I've changed "AEL Offline" to "ScreenScraper" (introducing my username and password) and when I rescanned my ROMs again the metadata wasn't updated, so I've deleted my launcher and started again and then the problems started and this is what my "kodi.log" says:

Anyone can help me? 

Curro88, I'm having the exact same problem as you. Adding a new NES launcher and trying to scrape metadata always leads to a crash. Did you find any solution?
