I've been using BlueStacks for years; I was stable on an older version of 5 (I think v5.13.100.1019). This morning, BlueStacks gave me a "Cannot start Bluestacks" error that wasn't fixed by a restart. I updated to the latest version and it said the same. Since I'd made a recent backup, I uninstalled it and tried a fresh install - now it starts up but won't let me restore my data (backup is from end of April) saying that it was made on a different version. I found an old installer for v5.13 but get the same "BlueStacks can't start" error as before. I updated to Nvidia drivers released yesterday but it didn't make a difference.

Is there any way to restore my backup?
