@Kingchen This is so weird!! Yup, it is in fact AutoItConstants.au3. And it is in fact in /include folder?

It's even weirder that replacing it to 1 has the same error. Can you post that error?

OK, it was supposed to be good code, but if it doesn't work, replace all instances of
UBound($posCollectors,$UBOUND_ROWS)
to
17
and see if this resolves the issue. If it does, it can give me a better idea why this is happening.

I am not at home right now, can't confirm the code exactly but that should be it.

Yes Kaz, i replaced the missed file in Autoit /include folder.

Replaced //UBound($posCollectors,$UBOUND_ROWS) or UBound($posCollector,$UBOUND_ROWS) has no good effect, same error    
But what you mean with ''17''?

For $i = 0 To UBound($posCollector,$UBOUND_ROWS) - 17

so? when yes, same error as above  

Replace UBound($posCollector,$UBOUND_ROWS) with 17 entirely.
