Server Change - License Issue

[weblion]

My Cllient changes servers. after moving the calendar files to the new server, when the Calendar page is accessed, you get a message on teh page that says

Expired or Invalid EasyPHPCalendar License.

When I go to setup, it tells me the License key is invalid in red font. When I click the link to get a new license key...it tells me

No additional licenses can be issued for this order number.

Please advise...my client is a public speaker and I need to get her site live again.

thanks!
