No, you no need a license to upload your project on iOS device. Unfortunately Remote method of uploading project is not reliable. Do you see progress bar during uploading your project? If not try to restart TeslaSCADA2 Runtime on your iOS device and try to reopen "Import for iOS" window. And try again upload your project. If it's not help try manual method by using Itunes for Windows.
Price list I'll send you by E-mail.
