I applaud you for reading the sticky post and providing the log file, much appreciated. However, the last line explains your situation "user:/SavedVariables/GS12Data.lua:615391: unexpected symbol near '<eof>" so you have corrupted files.
I do have an in game button to click that usually resolves the situation however, I'm not sure you can get the game to work well enough to click it so do the manual steps listed below.
1. Exit the game
2. Delete all the GSxxData.lua files (00 to 17) under SavedVariables
3. Delete the LibGuildStore.lua file under SavedVariables
4. Log in
Then wait for the refresh to complete. It must finish to test other things.

That is an abbreviated example of the notifications that will appear in the chat window for the refresh.
After the refresh finishes be sure you enable Detailed Information on Graph points. If you enable that and all the information is there for the dots then your LibHistorie cache was not corrupted as well and you are good to go. Then make a backup about once a week in case this happens again.
