Problem with cgminer

[bobbles]

I just purchased a Radeon R9 270x card and cannot get it to mine dogecoin with cgminer. I keep getting a "No devices detected!" error. I have the latest driver from AMD as well as AMD APP SDK 2.9. Any advice is appreciated.

Cgminer stopped supporting GPUs after version 2.7.2. If you have a newer version then it won't work. You'll have to download version 2.7.2 and try again.

Sorry I should have mentioned I am running 3.7.2.

Well this might be helpful for you to know what's wrong with the setup anyways  check the drivers the first thing to do

I'm pretty sure I've got the latest drivers for both the video card and motherboard but thanks for the advice.

OK that was a big help! I have a new issue though. If I go to a pool with low difficulty I am getting around ~460khs but if I go to a pool with regular difficulty I am getting 0khs. Is there some setting I need to change in my batch file?
