KLC authorisation problems

[Mordred]

I'm having trouble registering some of my KLC plugins I've just purchased. AI purchased the full package.
When the KLC was first out, I bought it along with the ms20 replica. I later sold it and transfered my account.
Last year I purchased the polysix and mono/poly and again, transfered them on.
Yesterday I purchased the full KLC plug in suite.
The m1, wavestation and ms20 installed and activated/registered fine but the other plug ins just installed and worked straight away without needing authorisation. Hence I could not authorise them on korguser.net. It's as if the old codes were still in my computers registry. I tried looking in the registry but couldn't find much and did not want to corrupt anything. I need to some how clear this to re register and authorise the plug ins and get them in my Korg account.
The legacy cell will not even load when installed.
I have installed and unistalled several times to no avail.
I am on windows 7 64 bit
I really need help please.
