Why can't I see my licenses after formatting my computer?
If you format your computer it will erase your licenses file. The licenses file can be restored, as long as your computer has the same machine name as before.
If you don't know the original machine name, you can log into your account at www.sidefx.com/services. Under License Manager, go to Manage your licenses and look at the SERVER column heading.
Once you rename your computer, reboot and see Lost licenses
