Well here is my advice:
1)It ate 2 days ago. Chill. Frogs can last up to a month or so without food.
2)Canned crickets isnt attractive to pacmans. I personally think its best used for turtles, and lizards that take dead food.
3)Worms are best here are what I use:
a)earthworms high in protein low on fat
b)Pheonix worms high in calcium and low on fat.
c)Goliath worms: high in calcium(higher than silk worms and pheonix worms) low on fat and high on protein(but very expensive!)
4)Make sure that you give it plenty of hiding places, that the dirt is deep.
5)Leave it alone for atleast a week for it to settle in. Some animals will take food quickly and some will take time to feed. Just try feeding it every couple of days.
For best feeding results feed LIVE worms. I prefer worms over crickets any day. Its my preferance though. I dont know what you or your frog prefer. My toads love worms. They even snatch it from my hand. My whites treefrog jumps onto my hand and snatches them from my hand. I can even try tugging them from him(It was an accident once. long story) and he will still try to eat it. Once I had a worm I was pinching on my fingers for the frog to eat. But I spaced out for some reason and then the frog was trying to eat it.
Hopes this helps. Congrats on your pacatron.
