Let me move this to the Acrobat forum for you, which is the appropriate forum for your question.
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.
I suggest you provide additional information such as the computer hardware you are using (type, processor, RAM) and OS as well as the versions of the programs you are using to create the form. This is useful information when troubleshooting.
