NERO: Unable to access shell manager

When I try and install Nero 9 Reloaded I get an error about 20% into the install, saying "unable to access shell manager" I just recently paid for Nero 9 Reloaded, and I I had to reinstall it on my computer due to an unrelated issue. I installed a new hard drive but still had my old drive with Nero files on it installed. I used the General cleaning tool to uninstall all files on my machine I even followed the removal instructions in post 18 of this thread

http://forum.my.nero.com/index.php?showtop...l=Shell+Manager. more then once.

I went as far as to uninstall my Anti Virus, Ad ware program and I disabled firewall. So I am extremely vulnerable to attacks right now but all willing to risk this in order to properly install Nero 9 Reloaded, being I paid quite a bit of money for this program, and Nero wants me to pay $1.29 a minute to help me install it I have posted in Nero forums and written Nero technical support. Can anyone please help me?
