Luac problem

[karurosu]

Hi, I tried using Luac to compile my lua scripts (i don't want it to be user accessible) but when I try to run the chunk it returns an error:

virtual machine mismatch in (my script file): size of number is 4, but read is 8

I tried in both PSP and Luaplayer win and got the same result.
WHat can I do to fix this?, thanks

I am using Luaplayer 0.15
