I have built a mining rig for litecoin
The mother board is ASRock 990 fx extreme9
I have 4 Gigabyte Radeon R9 290 cards installed.
I ran through this tutorial in detail:
http://litecoinstuff.com/tutorials/how-to-configure-xubuntu-cgminer-and-r9-290x-gpus-to-mine-litecoin-and-altcoinI got to the end and cg miner has the following error message

Anyone have any ideas on what to do?
