The problem: I can't add Mr. Sid image to any project and can't open project which already have Mr. Sid image Very thanks for Michael, Jeanne & Dennis and Ethan's answers Unfortunately I have no results. I was clean the temp directory, del all .hdr and .blp I increased free disk space to 1 giga (the image have 5 mb) I restarted the computer, the program, the project, the view, ... I tried to create new project But no way. Thus, I will reinstall the software. If somebody have anything against this way say now... Will be very appreciated!!! Will sum again and thanks for your attention. Luiz Romeu Architect
