Sincerly Look like the pdf was made like this. But if you can upload the file here i can tell you if there something wrong!
Post your question in the forum for Adobe Reader.
Looks like it was redacted.
I agree with try67!
Solution found :
1.- the AR file was OK, tested on other computer.
2.- uninstalled Acrobat Reader 9.2, cleaned registry using CCleaner,
downloaded AR 9.2 again and installed it.
Now I can read the text inserted in the before black fields of the AR document.
tHANKS FOR POST THE SOLUTION. THIS CAN BE USEFUL!
thanks for your solution!
