I had problems connecting to MtRed months ago, so I switched to BitParking (from reading another redditor's comment in /r/mtred). The site was up just last night, I believe.
I was hoping to use an extra computer to mine there, and I have been trying to reinstall Windows on an old laptop for this purpose -- I can't Linux well, and when I tried Mint and Diablo Miner, I got some message saying that OpenCL wasn't installed or something, even after following the directions from Google.
I have been having these problems also..
Try installing the new Catalyst 13.2 B7 drivers, they are faster than 13.1.
But it only installs OpenCL 64 by default.. you have to go into
C:\INSTALL\AMD\AMD_Catalyst_13.2_Beta7\Packages\Apps\OpenCL\ and install OpenCL.msi for it to be able to mine.
