Need help editing game file to fix game freezing

I've been having issues with my career mode lately. As best I can tell, the problem comes from an old satellite I don't remember launching called "Kraft launcher". It's the only object in my viewer that when I try to fly it the game freezes. I also see issues where the Space Center fails to populate any satellites then freezes, and lately RemoteTech has stopped establishing any connections. Can anyone help me completely edit out any "Kraft launcher" references from my persistent.sfs file to see if that fixes the issue? I saw the main chunk of info in the FLIGHTSTATE/VESSEL area, but there were two other references to the satellite that I found with a text search that I don't understand. Persistent.sfs File: https://onedrive.live.com/redir?resid=57F6038BEB1CECB6!153887&authkey=!ALe1sxIoyKW8TME&ithint=file%2csfs

Another potential issue is that I have some GameData references to Mods I can't see in CKAN anymore. Is that unusual? Does it sound like a problem?

KSP Version 1.1.2.1260

Mods according to CKAN:

• Remote Tech
• Precise Node
• Module manager
• Mechjeb 2
• KSP AVC
• Kerbal Engineer Redux
• ForScience!
• Custom Barn Kit (don't remember installing this)
• Contract Configurator, RemoteTech Pack, Bases and Stations Pack
• BahamutoD Animation Modules (don't remember installing this)

Other mods I remember installing through CKAN, that are in my GameData folder:

• Adjustable Landing Gear
• SETI ctt
• SETI contracts

Any help or advice you guys could provide would be awesome! Thanks.
