If that doesn't work, could be that your System software is incompatible. If you know it worked with another OS, consider changing to it, otherwise, decide if you really need that extension. About the Author Name is Marcus Schiermeier. I have a degree in Engineering Physics but decided to go into computers because it's more fun. I've been a desktop support tech for several companies for about four years now fixing every little problem that comes up on both Macs and PCs.
Macs are so much easier to work on.
The PC version of this is three times as large and doesn't do half as good a job of actually covering everything. If you have any problems or questions, e-mail me or phone me. I'll be happy to help you.
