Dear Rumors, First, sorry for my English. I'm 14 years old now and I live in the Netherlands. I downloaded and installed Iphone SDK an half year ago. Yesterday I started programming with it again. I thought; maybe I should download the new version so I did that after I uninstalled the old SDK via terminal. Then, I downloaded and installed it. It worked fine! But after I used it for I think 3 times it doesn't work anymore. When I try to start for example xcode or interface builder, it shows me a problem. Is there anybody who can help me? bye!
