Everytime I go to link to Taghira, I get this error message and the game exits:

Exception type: Access violation
Call stack (14 levels):
0x009158C2
0x7C816FD7
0x0066B9D9
0x01137624

0x0063FB3E
0x004F86AB
0x004F8621
0x004F8101
<end>

What does it mean and how do I fix it?

It's not all that strange! See Myst V: Main Branch and Access Violation/Stack Error Fixes With Win XP, one of the stickied topics at the top of this Forum.

Thanks. I found out it was a video card issue. I have to upgrade my video card because mine isn't supported by this game. Thanks for the help, and love the signature.
