First try to reinstall blockland, this might fix the issue if its just basic. The generic take out its battery and put it back technique. If that doesn't work, post a console log. It is located in My Documents>Blockland. Dunno about steam though. If you put this log we might be able to determine the issue.
I tried reinstalling like 5 times
He also posted a console log, lol.
Are you playing through steam or not?
Your third image shows you getting into blockland, is this random or why is the picture there?
Your reinstall might have reset the firewall for blockland, make sure to check it, it might be stopping you from validating if thats an issue
