Please let us know which program you are having problems with. Someone will be along to move this post to the appropriate product forum, where you are more likely to get an answer to your question.
You might also want to provide information on hardware, OS, any error messages being seen, program versions, information about what you're doing when this occurs, and anything you've done already to troubleshoot. This aids others in troubleshooting.
The Using the Community forum is for help in using the Adobe Support Community forums, not for help with specific programs. Product questions should be posted in the associated product community.
