Since I'm sure CAW victory would be off-topic in the babble thread, I'm posting here. Basically I just wanted to share my joy that a full reinstall actually did solve my problem. My world wouldn't export, even after deleting all the lots (the things on them, not that actual 15x15 space). So I figured it may have to do with the fact that my game wasn't recognising all my eps and sps. When I installed OLS something went wrong and I had to reinstall the other sps. And then some of my saves wouldn't work. SO, after all the hard work, it paid off! Yay!
