Tracker says my Mysql database table 'stone2.tracker_node' doesn't exist so I can't make pages, articles, content etc.

I installed Drupal 7.x and was pretty successful this last week but I have one major problem that just keeps popping up every time I try to create content or a page, article etc. I've seen this many times. The only difference between these other error messages is just one number. It is a message that looks like this:

Array ( [:db_condition_placeholder_0] => 5 ) the 5 is always a different number each time.

My Mysql database is called Stone2 but apparently the Table "stone2.tracker_node" doesn't exist as I keep getting this nearly identical error, as shown in the example below.

I am a newbie and not a programmer of websites or databases but I think the part that is the trouble is this part: -- "1146 Table 'stone2.tracker_node' doesn't exist:" -- but what do I do about it?

===================================
Example 1) I tried to create a new node, of type Article, with tags and publish it to the Main Menu, I assume on the Home Page. I've checked published and promote to front page and either alone.
But I got an error … Error message

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'stone2.tracker_node' doesn't exist: SELECT 1 AS expression FROM {tracker_node} tracker_node WHERE ( (nid = :db_condition_placeholder_0) ) FOR UPDATE; Array ( [:db_condition_placeholder_0] => 5 ) in _tracker_add() (line 264 of C:\xampp\htdocs\drupal718\modules\tracker\tracker.module).
The website encountered an unexpected error. Please try again later.
===================================
I found the module, at C:\xampp\htdocs\drupal718\modules\tracker\tracker.module, so the module exists but I don't know if it isn't working or why Tracker can't find the stone2.tracker_node.

Anyway, I was going to see if I could just re-download the Tracker module and see what happens.
But really, I don't think Tracker makes that node .... or does it? And I also had trouble finding the right module in a search. It seems there are a lot of files that have the word "Tracker" in their name. I was worried of getting the wrong thing.

I'm shooting in the dark. Anyway, I'd appreciate a clue.
Thanks. hkfletch
