Gerry,
You are starting off at a disadvantage since you are more than likely playing a demo scenario that has a ton of units.
I've been playing the PzC series off and on for a few years, and I still don't know everything. This series does have a learning curve. The more you read the manual and ask questions, the quicker you will hopefully understand what is going on.
If you think you like what you see, I think you would be better off buying a title that you have an interest in and only play the small sized scenarios until you better understand the game series and its rules. It is not a good idea to play large scenarios as a greenhorn because it will be too overwhelming for you.
Also, when starting out, be very careful as to which optional rules you are using. You can find a very well put together thread that spells out all of the different optional rules and what can happen if you decide to play with them activated.

Another helpful tip is to go under the drop down menu labeled "Setting" which you will see above you game map. Within the setting menu, make sure to check "Ask Before Advancing". By doing so, it will help prevent you from accidentally advancing the game to the next turn. It can happen to anybody however, if you have this setting activated, it will help prevent you from getting upset for advancing your turn by mistake.
Also if you have "Background Music" and "Sound Effects" checked in the "Setting" drop down menu, the game/AI will move a little slower which will hopefully allow you to be able to have an easier time reading all of the pop-up windows which are showing you the results of the battle going on between all of the different units. (The noise never bothers me, since I always play with my speakers turned off!) ;)
