Well - I'm about as far from being an expert as you can come. However, I do believe I successfully managed to back up my copy of the Flahpoint Gold Add-on/Update CD.
Instead of doing a 1 to 1 copy, I did a data CD. So, I copied the entire contents of the CD onto my HD. I then copied the "copied files" as a data transfer to a fresh CD and made sure to lable the CD exactly as the original was labeled.
I haven't had any problems yet. Hope that helps.
