Re-install Hoster, unable to re-install error already installed on 2 pc's, HELP

[gvmusic]

Hi,
Please help. I am trying to install Hoster and I am unable to re-install.

I have sold my backup system, before doing so I uninstalled Hoster then I wiped the hdd 5 times, then ran a system restore from the manufacturer restore cd.

I am buying a new system to replace that backup system.

In addition to that, I had a virus on my main system. I uninstalled Hoster and other apps, before doing a restore on my main system. I have performed a restore 2 times to make sure there are no lingering problems or virus.

I am now trying to install Hoster on my main system, and a msg appears telling me I have already installed the program on 2 pc's. This is not the case any more and I need this to work tomorrow as I am scheduled for a nightclub! Please help!

I am also worried, what if, in the future, a worse case cenario happens, my main system and backup system has a problem and I need to re-install my apps at a gig with no internet access? What do I do then?

Thank you for your help, I hope someone will contact me soon!
