I installed Carbide SDK two months ago and I tried the HelloWorld app. Everything worked well. Today I'm trying to continue and run the HelloWorld app again, but over the emulator window is displayed the registration window. So I had to generate serial key and ran the app again. But registration window closes itself very quickly without any notification. So I can't to input my serial key and I can't to run any app. I tried to reinstall, but nothing helps. Help pls.
