moving hoster from old laptop to new

[Groove]

Hi
If any one could help me with this.
i have an old laptop where i had hoster 3321a installed problem is it keeps over heating only stays on for 1/2 hour so i bought a new laptop i worked out that if i uninstall hoster i can then re install same hoster on a diff lap top when i went ahead with it it said "already installed on 2pc's" i sent a support ticket to MTU it came back "sorted" from MTU tried again still the same sent another ticket came back "install using this code ******* etc" tried that but it says "wrong code"
I have 3 setups where i use hoster for the public, 2 of them hoster lite 1 full version of hoster, thats the other copy of wich i want on the new laptop that i'm going to use in house, also the first hoster i ever bought, i did notice that i used a different e-mail back then, an e-mail i can't get to any more could that complicate things ???
I did mention this in one ticket i sent to MTU
Any help appreciated!!
