carbon rom trouble

[jzablocki15]

just flashed to the carbon-jb-v1.7 and also downloaded the latest gaps file from goomanager after I flashed carbon and tried adding the gapps file I got a bad file. It was already too late I flashed carbon so now im stuck with it the problem is i can download apps and use some but i cant use the browser and I had a backup for the old marketplace from which i was just going to update to google play but it keeps force closing same with the browser i also can not download from unknown sources I tried downloading a different rom and also different gapps. Now I would be fine but i have a mac. so my question is can anyone help me flash back to stock rom on mac or just keep carbon but fix the force closing???? help please!!!
