Tricky Paradoxes

A paradox is a series of true statements that, when put together yield a false statement. This is one of the most well-known paradoxes, so I must pose it as a scenario.

Imagine that time travel does exist and is completely feasible. There is an evil time Traveller who, in his travels begins to tamper with time so as to change the future. As he begins to tamper, more and more changes occur. In an attempt to create the most radical change in his own life that he can, he murders his own grandfather while he was still a child, before his grandfather had a change to concieve the time traveller's father.

If the grandfather is dead and has no children, how is it possible for the evil time traveller to even be born so as to go back and murder the grandfather?
