I would add that one cannot be in field-editing mode to enable the extended features....
I am having the same issue as Tony. I have enabled the usage rights using Adobe Acrobat Professional. The users are able to fill out the form and save a copy. However, after a few times of adding/editing data and saving the following message appears and does not allow the user to continue editing the form:
I came across this error before, under the following conditions:
My conclusions at the time were that if you are opening a Reader Enabled form on a computer which has the date/time set to a date that is earlier than the enabled date/time, then Acrobat throws the error.
Form enabled on first computer on 30/06/2009 at 2:13pm; but then opened on the second computer who's clock is set to 28/06/2009 at 10:34am, then Acrobat gets confused.
I found that once the second computer's clock goes past the enabled date/time then the form opens no problem.
Best solution is to have all computers working off the same (correct) time.
Hope that helps,
Thanks for your quick response. Both the computer the form was originated/enabled on and the user's computer have the exact same date and time. Our computers are synchronized using a central server. Any other suggestions?
I was just checking back through records and I came across it last March. Correcting the clocks resolved the problem straight away. I had not come across this error before that or since.
Might be worth a try taking your form outside of your network and test it on a standalone PC.
Here's my simplistic summary.
I have been using LCD for about 18 months and I NEVER had this problem.
Now with Adobe X, it is a constant bother.
Yes, there are various ways to cope with it, but before Adobe X, my Saveas and Send buttons always worked in Preview PDF mode...long before I applied the Advanced permissions to the final PDF.
So...something has changed. Adobe has done something wrong/differently in Adobe X and failed to explain it.
But thanks for all the posts. At least I know I can live with this problem. (And that it's not just me.)
For those who are using Adobe Acrobat X, the procedure has completely changed from what you may know from earlier versions of Adobe Acrobat Pro. This web page has information on the new way to handle usage rights: http://help.adobe.com/en_US/acrobat/X/pro/using/WS58a04a822e3e50102bd615109794195ff-7e0d.w.html
If you have both Reader and Pro on the same machine, it will cause problems.
James Houghtaling, is there any reason you could not have looked at Paul's response, decided you don't have Reader Extension server, don't want to buy it and asked "How do I Reader Extend the form in Acrobat?".
