Go Pro FX plug in suddenly stopped working

Hello,

Anyone else suddently experiencing a problem with the Go Pro FX reframe plug in? I have a massive project on the go and for months have been carefully crafting my shots using the reframe plug in on a 1080 timeline. All was going well but then today the image on the timeline only shows as its original 360 klaidoscope type image. I have tried deleting the cache, updating, shutting down and everything to try and get it to display right as it did before. I am using a mac if that is relevant. Any tips? Thanks in advance, James.
