Crashing on every server after loading datablocks with a runtime error

[Advanced Bot]

I have restarted my computer many times, and still get the same issue. It's a runtime that tells me that it has to terminate it in an unusual way. The console is here: http://pastebin.com/9G4Hjt48

Error reading PNG file:
 IDAT: CRC error
Try the following:

1) Remove cache.db.
2) Remove the screenshots folder.
3) Remove every .png file in the blockland folder and run the launcher.

Dammit, cache.db was the issue. Now I have to download every file again.
