XP / 2000 + SP4 problem

[brunojac]

I´m having a very strange problem that, I think, has started after instaling SP4 or some other Microsoft update.

 

My Max files opens and save in all operating system, but my lightscape files doesn´t opens in any XP computer in office.

 

Example: if I work in a max file, than export to ls prepare it, than calculate it in a .bat file (also occurs if I do in lightscape normaly)after that this file can be read only in a Win 2000 machine. Any Xp machine can open it.

 

Does anybody can give me a help?
