Is your laptop a different machine than the one you purchased the license on?

The license binds itself to a 'unique' computer ID. Each computer should be different (but there is a bug that has shown us that this is not 100%) Rob is very helpful in the transfer of the software from one machine to another, but I can't offer any suggestions on making the software portable, ie move back and forth between multiple machines. Normally, people purchase a second or third license for their additional machines, because this is required to run multiple copies simultaneously.
