Invalid HOSTid on startup

I am using a student version which I bought from uni. It has worked
about 5-10 times now comes up with "invalid hostid" box on startup, and
wont let me use the program. I re-installed it with a different
account, and same thing happened few days later?



Anyone know what is wrong, or how do I contact PTC to ask them?



Thanks

the hostid stuff is related to your network adapter/card



your not changing it around or plugging into other machines?

really depends on your licence type to.

Spot on mate.



I had been re-installing the drivers so today I got another host id sent out and used that, which works fine.



Thanks
