I'd kinda forgotten I posted this topic, but since then, I have gotten help, and figured out how to fix this. (Thanks to the guy who helped me with this) You have to first go to Edit>Delete by type>History. Don't ask me why, if you look in the script editor after you get the error message it actually tells you to do this, but i'm not sure the reason. Oh well, go do this, and proceed, and thinks work. Keep in mind, things like a solid shatter take forever to compute, so be patient.
Hope this helps whoever else had this problem.
