I Reinstalled the ignition software, and I backuped by using ".gwbk"and “.proj” files to restore .And when I want to open the screens in the designer , there is an error and said “Unable to open the window xxxx” and the details about the error are as below. The version is v7.7.2-rc1 (b2014102314),and the files were using the same version. What should I do to open the window in the designer.
