Seems like you have re-activate the product in the laptop instead of importing.
please use LTU before using the revit to make sure there are no exported license online. else revit will force a re-activation.
try to use LTU on the workstation to import the license. if it doesnt work. please use one of the manual method to the activate it again (or to reset the export)
