I saw this problem:
When i moved my flash usb kingston hard disk to my other PC ( which i choose for make it my router) it gave me free license 24 hours only,
and if i put the flash usb disk again in the first pc where i make license 6 on it it works fine again on level 6
I iexpected the flash usb disk work on the second pc because before i buy the license i read on the wiki on this link http://wiki.mikrotik.com/wiki/Manual:License
How many computers can I use the License on?
At the same time, the RouterOS license can be used only in one system. The License is bound to the HDD it is installed on, but you have the ability to move the HDD to another computer system. You cannot move the License to another HDD, neither can you format or overwrite the HDD with the RouterOS license. It will be erased from the drive, and you will have to get a new one. If you accidently removed your license, contact the support team for help.
so you say here that i have the ability to move my hard disk to another pc
what is my solution ?
