This all started today. Once I started up my blockland, it stopped loading and gave me a error message saying: Blockland Launcher- BlobContainer::snapshotBuffer(2) - sqlite error 'unsupported file format'. Ensure that 'Users/mike/Documents/Blockland' is writeable. It also gives me a OK button, but when i try to press it, it does not do anything. What should I do? BTW, I have a Macbook.
