Everything was working fine but suddenly lost sound for Cessna 172. All other aircraft seem to work Ok. I get the error message toward the end of the the loading process after the Finished Pre-Loading message and during the loading of the 172.acf. Here is the message:
Coundn't load the SoundBank! Master Bank.bank
I wasn't able to copy my massive log.txt, but here are the final lines before the crash:
FCG: Loading AI Aircraft Aircraft/Laminar Research/Cessna 172SP/Cessna_172SP.acf
ACF: Loading airplane number 3 with Aircraft/Laminar Research/Cessan 172SO/Cessna_172SP.acf
E/SOUN: Could not load sound bank at: L\X-Plane 11/Aircraft/Laminar Research/Cessna 172SP/fmod?MasterBank.bank FMOD Error:70
Then I get the error message that shows on the screen and the sim shuts down.
Any ideas on what happened and how to fix it???
