11556 and free version feature

[ColdAutumn]

I'm encountering the same 11556 issue. Even after installing the latest version 4.33.0, I'm still getting error 11556, and the software won't start at all. Since I don't have any data in the new software yet, I've opted to uninstall and reinstall it.

My next question is:
1,How do I manually import all the data from my previous/classic version step by step? My previous versions included many points, tracks, calibrated maps, some map items and online tile map configuration files that I created myself.
2,Are the features mentioned in the previous point supported in the free version? Or do I have to subscribe first? Of course, I actually bought the classic version in the past.
