Anyone else having an issue creating ne macros?

Macros are highlighted in black, I can save but nothing appears in chat when tested.

If nothing generated by a macro is appearing in chat, you can try deleting the Chat Archive. Otherwise, some more description or screen shots of the problem might help. This looks like a corrupted Chat Archive. A game's Creator is often able to fix issues with their Text Chat by  clearing the Chat Archive  (note: not  clearing your current Chat Log ). A GM might want to copy/back up the Chat Archive before the Creator clears it.
