You need to provide computer and software DETAILS
Details about your computer hardware
Details about your operating system and any other software that is running
Details about your EXACT work flow… in other words, every step you take and every option you click
Also, Since this is a USER TO USER forum, not Adobe support, and as the only way another user could reply is if they had that EXACT problem and also had a solution, you may need to contact Adobe for help
