Help please

I attended university back in 2007 and unfortunately i did not finish off my studies because I had too many resits. During my last term I got diagnosis with dyslexia and did not receive much help from the university. So my application to the course got with draw.
So many years have passed and now I currently doing an access course to go back. I have re-applied and applied to many other universities but now they are saying that I am unsuccessful due to action 2007 they called this academic failure. How can I over this ? Because since then I have improved and I haven even got my results yet.
