Forums mIRC Help -NickServ-your nick isn´t registered

Can I get some help with the following message I receive when I log in. I was not able to log in for some months due to healthreasons.

* /timer:invalid parameters
* /timer 2 not active

-NickServ-Your nick isn´t registered

Thanks for your help

Most networks have a 30 day or so, limit on unused registered nicks. This means that unless you login and identify to your registered nick at least once every 30 days it will become unregistered. Just reregister it (if it is still available. Visit the network help channel to register if you have any problems.
Good luck

Thanks for your help, I am in again
