Hi shay_df,
Yes, the file is Reader enabled, and yes you have to create an unsigned copy of the file before you can remove the Password Security.
Open 1244.pdf
Type in the Document Open password (111111) and then click the OK button
Select the File > Save a Copy menu item
Click the Save a Copy button on the conformation dialog
Enter 1244_noUR.pdf as the File Name on the Save a Copy dialog, and then click the Save button
Type in the Document Open password (111111) and then click the OK button
Select the File > Open menu item
Navigate to, and then select the local copy of 1244_noUR.pdf, and then click the Open button
Type in the Document Open password (111111) and then click the OK button
Select the File > Properties (or File > Document Properties in an older version of Acrobat) menu item
Select the Security tab on the Document Properties dialog
Select No Security from the Security Method drop-down list
Click the OK button on the conformation dialog
Select the File > Save menu item
