mac os 10/6/8 and adobe update

i have a mac os 10.6.8 and was instructed to download and install (update) a newer version of adobe.  i did that and now i cannot open/access legal fill-in documents that i require for my business.   i have not found the adobe site otherwise helpful and i know if i contact apple, they will tell me to contact adobe since this is a software problem.   i even tried to uninstall the recent update and could not figure out how to do it from the adobe site instructions.   help?
