Help please

Ive been trying to start bitcoin mining but every time a go and hit the start button it etheir just doesent do any thing or i get a nameerror: name 'openclminer' is not defined i am also using GUIMiner. This is very odd due to the fact ive already prevously mined on this machine the only deffence is now i have the entire program in another location wich shouldn't effect and thing"right?"

Does it mine, show MH/S and you feel the lag, and no shares get counted? If thats the problem, I fixed that by downgrading Catalyst Control with my amd gpu. If not, try re-installing your GUIMINER

Not it noes not display anything when i hit the start button. how do you install guimuner?

http://guiminer.org/ Click on the download, its not "install", re-download it and run it from a file that you chose, I would make a file on the desktop called GUIMINER with all the stuff in it, and run the miner from that and see if it works.
