[MAJOR UPDATE][V 1.2] Black Square TBM 850

Just hoping someone can help…
Had the BlacksSquare TBM since day one. Added the TDS 750, amazing.
Downloaded the relatively recent TBM update a while ago but been distracted with the Fenix. Came to fly today (TDS updated in the meanwhile) but limited avionics available. Especially no EFIS. TDS working okay. No default GNS 530 and couldn’t open the OFB either. I did some searching, deleted and reinstalled the TDS 750 but to no avail. Advice would be greatly appreciated. Thanks in anticipation.
