It's probably just what it sounds like: you've forgotten a } somewhere.

But without any code, or a minimal working example, to look at, it's impossible to tell.

MikTeX is not an editor. You want to post in the subforum for the editor you're using (assuming there is one).

Not sure why you're loading the enumitem package twice, but since you are loading it, you can just use the label* option for the subitems with the dot at the beginning rather than the end:

If you really want to write subscript underneath regular \cup, you could use the \mathop command, which makes its argument behave as a big ...

To make a new command local, it needs to be done inside braces, and the braces that are part of the \newcommand syntax itself don't count. So to make the definition of \temp used in \firstmacro get thrown away when it's done, you'd need another set of braces:


\newcommand{\firstmacro ...

I just downloaded the actual installer (install-tl-20110906) and the option is not available when I start the default, non-gui install process (via "./install-tl").

But it is indeed available when using the installation with GUI (via ...

Try loading the cite package: If that doesn't work, provide a proper minimal working example we can test with.
