Hello,
I encounterd a simmilar or the same problem.
For me it happens when I used a tokenized script that contains the right() function.
When I tokenize the scipt with other version than 4.61 and then run the tokenized script with 4.61 I get this error:

ERROR : invalid method/function call: missing required parameter 3!
Script: C:\Users\scmart\test.KX
Line : 2

The other way round (tokenized by 4.61 and run by 4.60) I get:

ERROR : invalid method/function call: too many parameters!
Script: C:\Users\scmart\test.kx
Line : 2

Thats my script I used for testing:
$text = "Hallo Welt"
right($text,4)

Hope that helps resolving this problem or helping others to understand thsi problem.

Martin
