After a short, few second power outage while playing blockland, I rebooted my computer, and tried to start BL back up, only to get stuck on the black screen that appears while it loads. I killed the process, and validated the cache files. It said that all of the files were fine, so I tried starting BL back up again, only for the problem to repeat itself. I then tried starting up my non-steam version of BL, and I got the same problem. How do I fix this?
