Question

can i use it on multiple computer? or it is lock to my first login computer?

and for paying the lifetime master package , for 159.99 £ if i pay with paypal with USD does it automatically convert over to euro?

so i have a laptop and a desktop , i will be able to switch between them. correct?
and is there any process to switch it like that ?

aslong as it is yours you can request a HWID change which are manually analyzed by the admins
