the only option is to buy completely new license and install it on your current hard drive (stoorage medium used)
i would suggest you to take out storage device and swap it with new one and save this one for another install as you will loose you current key if you overwrite with other license.
of course. just enter the current SoftID in the mikrotik.com purchase form and you will get the brand new L6 key. now connect with telnet and paste the key.
Hai fren,
as far as i know, with Mikrotik’s you will easy and nice to bla . . . . bla . . . bla . . . .
