Then sysreset has mIRC bundled with it, and that is forbidden by the EULA of mIRC (see /help license agreement). You should either dump sysreset for something more recent or contact the author of that script and explain these problems and EULA violations. mIRC 6.16 fixes a number of errors that can crash your entire mIRC, and many scripts posted here and on other sites will not work on older versions.
