Sims 3 update help!!!!

Hi,

I am trying to install Sims 3 Paradise and I keep getting this message:

Some of the files have been modified!
Please re-install

Should I reinstall or what should I do?

Thanks,

Katie

I used to get that problem, have you tried turning off then turning on your computer ? 
Or maybe patching using the manual patch ? 
That's what worked for me !

I will give it a try and see what happens!

Thanks!

It worked!!! Thanks a million!
