General :: Yum Update - Cannot Retrieve Repository Metadata

Just starting out to use linux and of course, everytime I first install an OS, I download 2 things, flash and Chrome. Chrome works fine, but flash has been giving me a lot of problems. I've downloaded the yum file from the Adobe website, and unpacked it using the GUI, yet it still didn't work. So I started googling how to use yum. So I followed some directions and tried doing

Code:
yum install flash
this is what I get:
Code:
[root@localhost testpilot]# yum update flash
Loaded plugins: langpacks, presto, refresh-packagekit
Adding en_US to language list
[URL] : [Errno 14] PYCURL ERROR 6 - ""
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: adobe-linux-i386. Please verify its path and try again
[root@localhost testpilot]#

But thats not the only problem, I think my repo's are messed up or something because look what happens when I type:

Code:
yum update
Code:
[root@localhost testpilot]# yum update flash
Loaded plugins: langpacks, presto, refresh-packagekit
Adding en_US to language list
[URL]: [Errno 14] PYCURL ERROR 6 - ""
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: adobe-linux-i386. Please verify its path and try again
[root@localhost testpilot]#

As you can see, its still trying to goto the adobe website, even when I type in a completely different command from getting flash. So I guess I have 2 questions:
1) How can I "restore defaults" on yum so that I can actually use it
2) How can I install flash?
