Same thing happened to me. I created a new HD menu by mistake in my SD project and then quickly deleted it. It was gone from my project until I went to build a DVD, and the system found the menu and the inactive buttons during pre-build inspection. I couldn’t find the menu in my project window or my menus window. I tried to check for errors again and the program crashed. It continued to crash on the proceeding attempts to build a disc. I cleaned and deleted the cache database twice without any success. I finally bypassed the entire check project process by unchecking every option in the inspection list. I was able to build a disc successfully. After burning a few discs, the HDMenu showed up in the Menus window. I can highlight the menu from the list, but it won’t delete! I can delete any other menu in the list, but not that one. I can delete the four linkless buttons it contains, but not the entire menu.
I have Adobe EncoreCS3 3.0.0.268
My burned DVDs work flawlessly.
