Compact Flash is a Media Card Reader Slot.

The testing did not find any media in your memory card reader.

And the other error is probably because you didn't have a data CD in the optical drive during the testing.

You can go here and let it check the version of Flash that's installed and tell you which is the latest version that's suitable for your system.

You may want to run the Adobe Flash Uninstaller before installing the latest version. That's the correct way to uninstall Flash.
