Hi,
Download the new beta version and when you replace the mirc.exe file with the new beta version 7.76.2691 and start the mIRC, verify that the mIRC is not available in the DCX.dll file.
* /dll: unable to open file 'D:\newmirc\scripts\dlls\dcx.dll' (line 11, script3.ini)
alias dcx {
if ($isid) { returnex $dll(scripts\dlls\dcx.dll,$1,$2-) }
else dll "scripts\dlls\dcx.dll" $1 $2- <<<<<------- line 11
}
