Changing maps using triggers

[Wezthal]

There is this native:

• Set Next Map
  • Options: Action, Native
  • Return Type: (None)
  • Parameters
    • Map <String>
  • Grammar Text: Set the next map to Map File
  • Hint Text: Sets the next map to be run after current map finishes.
  • Custom Script Code

But I can't get it to work.

I made this simple test trigger:

• Load Next Map
  • Events
    • Timer - Elapsed time is 2.5 Game Time seconds
  • Local Variables
  • Conditions
  • Actions
    • Game - Set the next map to "GE Test 001.SC2Map"
    • Game - End game in Tie for player 1 (Hide dialogs, Hide score screen)

But it won't work. I've tried different ways to type the file path, but none of them seem to work. It gives a blackscreen for a while and then pops up the SC2 login screen with a message "Unable to open map.".

So far I've tried these:
"GE Test 001.SC2Map"
"GE_Test_001.SC2Map"
"Maps/GE Test 001.SC2Map"
"Maps/GE_Test_001.SC2Map"

If anyone gets this to work, it would be appriciated if you could tell how you did it, thanks.

EDIT: (Darn, should've posted this to the Galaxy Editor Help Zone.)
