Tried to upgrade to 3.303 from 3.300 but lost hoster

[pelletmon]

Hi guys.When I did the install,a message came up saying I must uninstall all prier versions of hoster to install 3.3003.So I clicked on yes and hoster went bye bye.I tried to install 3.303, (paid 39.95 for the download from my account)and got the 2computer thing. I have a gig tomorrow night.I do have my disks for backup,but haven't used em in a long time and really don't want to if I can help it.Could someone please reset the registration code so I can get my upgrade? OR,if no one gets back to me before my gig,would it be totally insane to buy the downloadable 3.303 at full price just so I can work tomorrow, and plead my case to MTU when I can get in touch with them? Bevis,you may haft to consult cornholio on this one.Thanks
