With the helpsuggestions of someone on the A* community I have uninstalled FTM, deleted all the files left in the program folder, rebooted the PC, reinstalled FTM, installed the patch, rebooted PC, it appears to be fixed.
Actually I'd go as far as to say improved. I was unable to install the patch as it caused the program to crash (it wouldn't even open the program).
I've got a feeling my mobile phone software was probably involved as when I tried to install the patch the menu for the phone studio would come up, I've uninstalled that (I don't use it and can always put it on my other computer if need be instead) as well today and the FTM patch installed just fine.
Oh well, who knows why it stopped working, but at least it seems to be fixed now.
Thanks for the suggestions =)
