We bought a LiteSpeed License Key: xxxx-xxxx-xxxx-xxxx through SimpleHelix. Saved it as "serial.no" file in the installation directory. But I got this error. 2010-06-08 12:24:16.961 [ERROR] [LICENSE] License key operation failure: DT.7: The maximum number of server(s) can be installed with this serial number has been reached. If you want to migrate a license used on another server, please consult the product manual regarding how to transfer a license. count=1 [ERROR] Sorry, installation will abort without a valid license key. Should I get a Serial Number from SimpleHelix? Or only this License Key?
