Do these work on multiplayer?
Of course! The only EUDs that will not work safely on multiplayer are the conditions put under the "Local Only" tab. Note that only local conditions can cause problems in multiplayer; you can use the "Local Only" actions to your heart's content without worrying about a desynchronization in your game. See
Section 5 of the
EPD tutorial for more details on synchronization and how it affects multiplayer.
What about Mac users? Are these safe to use with them?
Macs and PCs have different ways of calculating some EUDs due to the endianness of the operating system. Included in this program's export feature is the ability to generate Mac-compliant EUDs based on the information I know regarding Mac EUDs (special thanks to jjf28 and Lanthanide for the research going into that aspect), but as I have no method to verify the outputs (and I'm fairly certain some of them are wrong), it's currently in beta stage. I would not rely on the program to generate Mac EUDs and instead do them by hand if that's an option. See
this topic for more information around Mac EUDs.
How come EUD Actions don't work?
This may be referring to one of two things. First, EUD Actions (EUDAs) will not work without an enabler of some sort. I would recommend using FaRTy1billion's
EUD Action Enabler program for this. Second, if you're copying over EUDAs to SCMDraft's text trigger editor, you'll notice that it won't compile. This is because SCMDraft's text trigger does not support EUDAs. You can still manually enter these triggers into the classic trigger editor, though, or you can use another export function (MapExport being provided graciously by FaRTy1billion) to get these actions into your map.
So I heard about these things called EUPs; does this program do that stuff too?
No. EUPs are a completely different method of writing to StarCraft's memory, and as such, they require a different method of calculation. If you're interested on the subject, I'll refer you to the following topics:

I'm going to need more details on exactly what you did. What trigger did you write when this happened? What was the last action did you do when it broke? What do you mean by "is not working anymore"? What is your operating system, and were you using the latest version of the program?
Also, I apologize for the delayed response; I don't get notifications when you leave a comment here, and I didn't see your comment until just now by chance. So if you'd like to send me a PM instead, I can reply much quicker to help sort this issue out.
