Acrobat User Community Forums

Hi,

As a student,I am an average level user of acrobat...I earlier had a 7.0 and recently got 8.0 installed..it worked perfectly fine for 15-20 days..but all of a sudden..past two three days,as i try to open any  .pdf it closes down within a span of 10 seconds or so..
also if i try to open distiller..it says acrobat not activated...I dont understand..
my lot of amterial is in pdf format and i am having no access to it..:(
i have event tried reinstalling the Acr8 after uninstalling it fully..
but the problem seems to persist..

any help/comments are welcome..
