If you can't use all functions of the application, it means that the software is either not correctly installed or it is not compatible with your system. In order to fix the issue, uninstall the program and then install it again. Also, make sure your computer runs Windows 98, Windows Me, Windows NT, Windows 2000 or Windows XP. If the problem persists, I suggest you upgrade the software to AxtraxNG. As you can see on the FAQ section from the official web page, you're allowed to do this operation.
