Sigma Plot Fail

I've been using Sigma Plot to make all the graphs for my papers but I recently discovered that my license expired and I can no longer run the program.  The license is held by my work so I asked the IT guy to look into it - hopefully he can fix it.  If not I'll be remaking all my graphs in Origin because for some reason my company has (had??) licenses for both Sigma Plot and Origin.  I'm just hoping it will all get resolved soon.
