Cant get a license

[squintnic]

This is happening to me again, on a deadline and my second brand new license that has been working for a few days juts fine has dropped out
Have restarted and everything I can think of

Any ideas ?

This is honestly such a bloody pain in the ass - this is a paid product! Why does it drop out so often

EDIT

i reinstalled vray and it works again
even so its a repeating issue and i dont understand why it cant be fixed? please check out other software for ideas about licensing
cheers
