(adsbygoogle = window.adsbygoogle || []).push({}); So I left my pc on last night and turned ps3 off. got on this morning, installed react psn and one dlc that didn't even work, and now can't connect via target manager.

Try refreshing target manager. If that doesn't work, restart your pc and open up target manager. If that doesn't work delete the ps3 on target manager and make a new debugging station.
