In your screenshot here you posted an error. But in the screenshot you sent to support your error was slightly different. I suspect the reinstall actually did change things – but that that there are still other things yet broken.
Since this all happened after a Time Machine restore I think it’s very reasonable to assume that something went wrong during that process.
I would strongly urge you to create a new backup of your data (not just this file or Stacks or RapidWeaver but all of your data). When things go wrong with a backup/restore then it can be catastrophic and it’s always better to be safe than sorry.
OK – that that out of the way, I think what I’d recommend as a way forward would be to start with the basics and verify each bit works in turn. Don’t proceed to the next step until you know the previous one works. In this way we can build up from working system until we find each broken bit.
- Download and Reinstall the latest RapidWeaver. And run it with no add ons at all installed. Make sure that you can new/save/open/preview/export a new file – don’t attempt to open your previous files just yet – we’re just verifying the basics first.
So, if you’re here – the we know RapidWeaver is working and you can move on to your add ons.
- Download and Reinstall the latest Stacks. Make sure that you can create a new file, add a stack, preview, save, open.
So, if you’re here – then we know RapidWeaver and Stacks is working and we can move on to other things.
- Install other add ons and test in turn. For now, you should try to limit this to just those needed to open your file.
So, if you’re here – we know that RapidWeaver and all your add ons are working.
- Now open your file and see if things improve.
If things are working, great – we fixed it by reinstalling things – if not then we can be certain the problem is that the data in the file is somehow corrupted by the TimeMachine backup/restore process. If that’s the case, then it might be wise to take your machine/disk to expert (Apple Store) to see if there’s anything that can be done to restore the data without errors.
