JJSPLOIT not downloading on anything.

I've had this problem where I play one game and it okay sure works but like if I play a different game and use the jjsploit again THEN it says couldn't find the DLL and to download it again, but it wont download again. Id have to wait 3-6 days to use it again. If I redownload it, fix it, or do ANYTHING it just miserably fails and makes me a little sad, do you have any ideas?
