I have the Ultimate version via Steam, which I until very recently had last played a couple years ago - before the community patch got turned into an official one. I got an itch for it recently and reinstalled it, and after some fooling around I wanted to look at the tech trees. Unfortunately, Galactopedia is misbehaving, and I can't figure out how to fix it.
Galactopedia works normally when viewing the original game or Dark Avatar files. When I switch to Twilight, it gives me this error, with this full text. The program will keep running if I tell it to continue, but does not display functional trees - this is what it shows instead, which is neither navigable nor helpful. If I close Galactopedia after this and then later try to reopen it, it crashes before opening and gives this error. This happens only after attempting to view the Twilight information - if I only view the base game or Dark Avatar data, Galactopedia has no issues being closed or opened.
Unfortunately, I have not been able to find much information on my own. The tech trees haven't been put online, even on the wiki, so I don't have a functional alternative for looking at them. There have been very few reports about Galactopedia not working for anyone, outside the one in the sticky thread - I tried to follow the advice given by chris0101 at the end of that thread, and while erasing the registry files Galactopedia creates allows the program to open again, it neither allows it to display Twilight's data properly nor keeps it from crashing if opened a second time unless the registry files are cleared again.
I've been using the Galactopedia version provided here, as per its sticky thread, and have already tried deleting and replacing it. I've verified the files through Steam multiple times, and completely uninstalled and reinstalled the game. The problem remains.
Ideally, I'd like some input on how to fix this. Alternatively, I'd consider any sort of functional alternative that's not digging through the XML files the slow way. But any help would be appreciated.
