what if i have Soldat registered in my computer, but I format my system or I buy a new computer??? how do I keep Soldat registered???

Re-install your registry key.

To keep your soldat registered. Just have a copy of the key save on a CD or Floppy. And when you have a new system or computer, just pop the CD or Floppy in, and re-install the registry key like Lapis said.

or do as me ;D print it out and stick it on the wall for extra security ;)
