Here's a tip to try. Grab a pinch of the toby and squeeze it between your thumb and index finger. If it sticks together, or flat out just feels wet to the touch let it sit out for a time. Check it ~15 minutes or so using the same trick. Just keep on mind that there are quite a few blends that will have PG in them to maintain moisture, and some blends (heavy aromatics) just tend to be goopy anyway from the flavorings (casings) and toppings in them.
Since you didn't state how you loaded your pipe that may not be the culprit at all, but there are some methods to check out on the web and you may employ several different techinques depending on the type of leaf you're enjoying.
In any case, keep a lighter or matches handy, pipes almost always have to be re-lit at some point during the smoke. Sit back and enjoy!
