Probably you have been getting this error message when clicking on the .001 download links I've posted:
"Archive Download Blocked - The file you attempted to download is an archive that is damaged or possibly encrypted. MediaFire does not support unlimited downloads of broken or encrypted archives and the limit for this file has been reached. This file may only be distributed from a premium account."
Apparently now they don't allow unlimited downloads of split files hosted in free accounts. =_= But for some reason it only applies to .001 files. I've tried renaming them, but it doesn't work. I've tried copying them to a new account, but that doesn't work either. So I'm afraid I'm going to have to re-upload them with a different extension, and I don't know if that will work. *crosses fingers*
