This happens either because the files you want to import are not fully supported by the program, or CAMCAD Pro is not installed correctly. In order to fix the problem, right-click the files you want to import, press Properties and click the General Tab. The file format will be displayed next to the Type of file. If the files are supported by CAMCAD Pro, remove the software from your computer (Control Panel > Uninstall a program) and install it again. Also, you can use 800-592-2210 phone number to get in touch with the support team.
