Help with unsafedisc 2.40.10

Everytime I try to use it with any Safedisc v2 protected exe I keep getting 'random error'. What the heck is a random error and how can I correct it?

I am trying to unsafedisc my Civ3 exe because I can't play it with this stupid safedisc protection on it. The splashscreen pops up then fades and I am still in windows. I had this same problem with PoR.

So any help is appreciated.
