I am a new model railroader. i have an n scale 4-0-0 locomotive and tender. All of a sudden I cannot get all the wheels of the locomotive on the track, even using the rerailer. Any suggestions?
The N-scale 4-4-0 has a reputation of being pretty finicky. However, it appears to me that your problem is that the wheels are not properly in gauge, a common problem. I'd recommend getting an NMRA (National Model Railroad Association) standards gauge (http://www.modeltrainstuff.com/product_p/nmra-98-8.htm). It will make sure all your equipment's wheel are correctly in gauge.
If the wheels do turn out to be in gauge after all, the problem is likely more bizarre and more unique to your particular locomotive.

I agree with Tim here on this one; however I'm going to go at it from another direction.
You say

From this, I am going to assume that at one point you could re-rail it properly and the loco would in fact move down the track. Now, that does not "seem" possible as when you rail the loco it does not move.
Correct me if I am wrong.
First things first.
I would caution against using a rerailer with ANY traction tire loco, steam or diesel, and here's why.
As you push/drag the loco down the rerailer and onto the tracks the traction tire turns on the stationary driver. This action breaks whatever little seal there may be and, in effect, loosens it from the driver. This action alone is enough to "throw the tire".
If it hasn't already fallen off from the sliding action down the rerailer, it will soon after, from sliding it onto the track.
Look to see that all the traction tires are still on the drivers. There should be one on each, for a total of 4.
Second,
The wheels on the tender do not use a conventional axle
There are 2 trucks under the tender. The forward and rear wheel of each truck is tied together via a contact strip/spring assembly.
The tender wheels float freely from the axle mounts.
As of yet, I have not had mine apart.
If it's possible to gauge the tender wheels at all, it will require surgery.
The driver wheels are isolated from the hubs via a press fit (metal on plastic).
They, and the pony truck wheels, can be gauged in the normal fashion by gentle prying.
Be careful if you decide to do this, so as you do not mess up the quartering of the drivers.
The motor is in the tender and picks power from its own axles. A drive shaft joins the loco and tender turning the geared drivers.
In summary, check to see that you have all 4 traction tires and that they are properly in place.
Then, check the drive shaft.
Cradle the loco and tender upside down and apply power to the tender wheels, one left, and one right.
Listen for the motor, and observe that the loco driver wheels are in fact turning.
Try this, see what you have or have not.
I will comment further after you report back.
P.S. All this, assuming you meant to say 4-4-0.
