Key store works in corona build 2731 but not 2970

RESOLVED - Not sure how but after many attempts switching to different key stores (including the debug key store), then exiting corona, then restarting, it eventually accepted the required key store password.

I’m having some issues with one of my key stores.

My key store passwords work fine if I try build with corona 2731, but if I try to build using 2970 I get the password is incorrect errors.

Any advice on how to clear corona’s preferences cache (or where ever it stores key store info) so that the key store will work in the latest corona build?

Cheers
