So I followed this guide step by step: http://www.mooege.org/topic/144-newbie-proof-easy-as-pie-tutorial-how-to-use-mooext/

 I'm still getting error 3003 "unable to connect". Any suggestions?

"any suggestions?"
Yes, don't make new threads to make an already answered question, or if FOR SOME REASON your issue is new (because you don't provide any explanation whatsoever) you still shouldn't make new threads.

Please someone (Myst?) delete this thread, thanks.
 

Well if its a new question and the user hasn't found a solution for it through searching, they should make a topic about it, rather than posting in a thread that has 50million pages worth of posts.
If people make new topics after they search for a solution and find zero results, it makes it easier for other people you have questions or who seek help to look through the topics rather than pages worth of posts.The single topic creates focus on a given situation, rather the "noobs post here" topic creates a broad amount of different questions and answers, that although good, can be cumbersome to look through, even when using the search feature.
But anyways Lirwin2, see if any of these search results help:

okay i figured it out, to fix the 3003 error take the MPQ's from their folder and drop them all into the MPQ folder in the assests folder in the mooege directory, if they're in their own file it wont find them... they must be in the same directory as the 'IMPORTANT' file.
