There are 2 ways
to see if it installed, and I do not know which
version of Widows you have (2000, XP, Vista) or which "Browser" you
have(IE or Firefox).  ***** So- 1st way-.

 
Click Start
-to All Programs
and look either by for the game title
under Playfirst. If it's downloaded correctly, it will be there
, but I find this  can get very cluttered if u have alot of games downloaded.  #2
.- Start
-Control Panel

to 
Add or Remove Programs


-which includes any games installed
on your PC. Check if it's in there. It is set up A-Z usually, so games are easier to find. If it downloaded right, (and I am assuming you
downloaded it and didn't get an icon) it will be listed
. However, the only way

you can
access it


is from (method #1) Start-All Programs, find the game and play it.  BUT if it
isn't in there, then re-download it. 



If you really want to  have an icon, then

just re-download it. When it is finished, it will leave you an icon and you Will NOT loose anything saved in the game. The game won't install twice from the same game company. -and then you will have an icon.



Good Luck, CSPMBS***************NOW I left NO SPACE(S) or OPEN  AREAS between what I wrote.  Why does my answer show up like the way it did????

Check in your PC's history and see if you can locate that particuliar page...Every page you visit is stored there.  How long the History is kept depends on how you set your PC up.  On my Internet Explorer, the history is only kept 2 days.  On my primary browser, Firefox, I have it set up for one week.  Where the History is located also dpends on which browser you use annd on which system.
