Hi there, I hope it's the right section where to explain my problem. It took place when I upgrade the system from XP to 7, the version of Acrobat Pro X has always been the same. This is what happened:
1)The old pdf files (taken from the backup done before the upgrade of the OS) aren't manageable, the watermark (just present or applied at the moment) takes place above the text of the pdf, covering it, the options of the program doesn't help, if I choose to put the watermark under the text it disappear from the screen and from the print;
2)The pdf created from scans has the same problem.
Only if I create a new pdf (for example form a word file or anything else) I'm able to manage the watermark and choosing the "under the page" option it doesn't cover the text.
Obviously I reinstall the application but the tests that I've done on many computers give the same result.
Every advice will be appreciated, thanks.
