Hi can anyone help me?.... I have this program that only give me 25 minutes and save and print is disabled. After 25 minutes it say this demo version has expired...etc...then you hit ok and program end. I found out where it give you 25 minutes I tried to change it to something like 2 hours, but when I do that and time reach 25 it says this program performed illigal operation. etc. can someone help... program is by Bytronic. thanks

What kind of illegal operation is that? When division by zero, look around, there could be a checking routine for that value. Or the proggy might use a CRC check....

Thanks for replying, macilaci. but I'm very new at this maybe u can check out the program, and see for yourself what I mean program is by bytronic program is a ladder logic, please reply if u can thank you.

I can't help you at this point, you have to go deeper and for example show us the listing where you suspect the protection to be located.
Otherwise this is like a direct crack request and its not the purpose of our work, if you're a newbie you can start of the fravia archive server, do here a local search concerning time trials.
regards,
