Hello. I would first apologize for my poor english.
I have kinda the same problem. Yesterday at work, I launched mIRC with -portable and entered my registration key. So a section [user] with the registration info appeared in the mirc.ini file and nowhere else in the registry. Perfect !
Back home, I launched mIRC again... and the dialog "not registered" came back !
So I re-registered. And this morning, at work, again the same problem. But the [user] section in mirc.ini file is still there. Is it because the drive letter is different at home and at work ? Or because Windows versions are different (2K at work, XP at home) ?
Moreover, the lock settings where never saved : I see the section in the mirc.ini file but it seems not to work.
Someone to help me ?
