Are you sure your blockland folder is not set to read only, and if it isn't is blockland.exe allowed to write to it?
Like I said, I'm on a Mac. I don't know how familiar you are with Mac OS X, but every name under the
Sharing and Permissions pane is set to read & write. I don't know about Blockland.exe (although it's probably called Blockland.app on a Mac). I cannot add applications to the list of people allowed to read & write, only contacts. However, my account—the computer administrator—is set to read & write to the Blockland folder.
Check it:I don't think the fact that I'm using Blockland on Steam has anything to do with it. I used to be able to save even with Blockland on Steam. Could it be the OS I'm running (Mavericks)? I used to be able to save when I was using Snow Leopard (10.6.8). Um, I'm stumped. Please let me know what you think.
