 * Hello,
 * I installed your plugin and bought pro API license in order to remove the watermark.
   Everything worked fine with three forms I created two days ago – watermark was
   removed.
 * However, today I am not able to change fillable pdf documents in existing forms
   or upload them in the new ones. I am always getting API Error message? Can you
   help me with this problem?

 * I do see errors in the logs. It looks like your PDF file is password protected.
   Please decrypt your PDF file and try again.
 * Adding PDF password protection support is a planned feature. You will see it 
   implemented in a few months.
