Ok, sorry for the delay, I'm really busy checking the support thread (
http://www.mohadmin.com/nuke/modules.ph ... sc&start=0). If what you mean is if you can check a server without having his rcon password, not, you can't.
The error 6 Overflow should be a thing of the past with the new version (the download link is still the same).
