I updated Acrobat Reader to X version on my laptop recently and found something wired. When I tried to open some PDF file including name "CRB" (either the folder path or file name), some error appeared said "Before proceeding you must first launch Adobe Acrobat and accept the End User License Agreement".
After changed the name to some other one (without CRB), the file could be opened properly. Or, if I opened the Acrobat Reader X first and then open the file using menu options, it could be also opened.
Very wired, right? Did anyone meet the same problem?
