Norton Internet Security 14 "has issues" and is giving me issues. lol

For Norton Internet Security 2014 ..I bought this online on a site that has deals on anti virus etc and got the product key no disk. It was for 1 pc use, really  it is 3. (according to my norton account and the application on my desktop.  When I first went to enter product key, it had 1 already there in the space, I deleted and entered new 1.  I have used Norton since my first pc in 2000. Back when you got a free year when you bought a pc...I have had 360 and the suite in the past. Or just called Norton antivirus.   Just wondering

also...every day since I installed , about month and a half ago, When I turn on pc , it has product service dependency error. First time, I downloaded fix tool for that, Now it has 2 errors a day, Prod serv one and one saying I need to restart to run fix.  on a side note, this seems to use a sh_t load of space like the other Norton anti spi vir. mal. products and not work as well and less features.  Thanks
