Submit button on fillable PDF doesn't work on all computers??????

Question

I have created several fillable PDF's for a medical office which has a submit button at the bottom. The button is supposed to send the completed PDF to the office admin's email. It works great on my computers in the office, and on a few other test computers I've ask people to try it on, but I received an email from the office admin today saying that an important VIP tried filling out one of the forms today and it didn't do anything at all. Also, another person at the medical office tried filling out a test form and submitting it and they said "Once we hit submit, it did nothing!"
What do I do? I am at a loss and this client has paid for all services and I am stuck!!! Please help...
Here is the site and all the paperwork. http://ocmedicalgroup.com/patient_info/patient_info.html
I can email all original PDF's if needed.

Regarding the security, you can set up the form to submit securely to a web server, and submit just the form data, which can later be easily imported into a blank form to create a filled-in form. The way it's currently set up, you have to Reader-enable the documents, which allows Reader to save a filled-in form. But there are licensing restrictions that go along with this. In short, if an enabled document is distributed to more than 500 recipients, as it is when posting to a publicly accessible web site, the licensee may use data from no more than 500 instances of a returned form, including hard copies. You as the developer cannot supply Reader-enabled documents to your client for their general use - another licensing restriction. They will need to purchase Acrobat to enable the documents themselves. All of this is avoided if you set up the form to just submit the form data to a secure web server, at the expense of maintaining the server.
Regarding the problem with getting what you currently have set up to work, it all depends on the particular user's setup. I would say the minumum requirement is Adobe Reader or Adobe Acrobat, preferably versions 8-10. If they don't have a working email client, it will allow them to save the file on their system which they can then manually attach to an email. This is so folks can use a web-based email system to send the file.
