Well, you say you've been using mIRC for 7 years (in another post), and yet now all of a sudden it's not working. Therefore, one would think it's a problem on your end somewhere. Khaled hasn't made your mIRC break. As much as you might insist you haven't changed anything on your end (in the past 7 years!), it is my experience that the user probably has.
As for a refund, well, that's up to Khaled...
Regards,
