FATAL ERROR: Could not load script file.

[daortir]

The RemoveTimer function is, according to your script, supposed to remove a timer called "TimerEvent_*"
And your timers are not named TimerEvent, TimerEvent is the function they call. Fill in the "" in your AddTimer functions, and then you will be able to use the remove timer function on your named timers.

Not sure if I made it clear x) 
Basically in AddTimer("name_of_the_timer", time until function is called, "name_of_the_function");
you have to add name_of_the_timer because this is how the RemoveTimer function will know which timer to stop, instead of searching for the function.
