Re: I installed installed Adobe Acrobat XL Pro. on my Mac. I did it for a trial a couple of days ago. Now i don't half access to most of my documents and saved documents. Should i uninstall it? if so will i loose any existing files prior to the download?

To be sure you don't get bit by something in these cases, particularly with business documents, create a backup of your harddrive. That is a good business practice even without the issue you have raised and should be done on a regular basis. Then, if something breaks, you simply restore the backup.
