Trouble with missions

I'm sort of new to Uplink, but I've already caught up what is what. But there is trouble with those missions where you're supposed to frame somebody for a computer crime or bank fraud. I modified the logs as they said but the guy never gets caught. Can somebody help me with this?

Do not use too many bounces, or the guy who's tracking you will give up before the end.

What you need to do is make your first bounce through InterNIC, do the stuff, then use the log modifier at InterNIC and point it to your target's computer.

The box said Windows 95 or greater...so why doesn't it work on a Mac?

Thanks, it really worked!
