Please post script problems in the correct forum. This is unlikely to be a bug in mIRC and posting it in the bugs forum just causes confusion.
Also, scripts that are not updated will eventually fail either due to changes in newer versions of mIRC or, in some cases, newer versions of your OS. If you are not able to update the scripts you use yourself, then it's a good idea to use only scripts that are updated fairly regularly or at least have a strong following so that someone else will update it if needed. Otherwise, you are likely to run into problems like this. And with large scripts like that, you won't always find someone willing to troubleshoot it for you if they aren't also using it. Be grateful that jaytea is willing to do so.
And just a quick glance at that script tells me that it wasn't written all that well and could probably be cut down in size by at least 50% and made much more efficient. jaytea's fix above gives you an idea of how inefficient this script is. You might want to contact others who use this script and see if any of them know how to script. Maybe one of them will consider writing a new script to replace this one.
