The trouble sighting in and how the gun fell most likely threw the scope off. Make sure that the reticles are intact. How far off are each shot and is there any pattern to the shot string, all left, right, low ect. If you have a pattern then just adjust the scope to the bullseye. If the pattern is all over the place you may have loose scope rings/mounts and if it were me I'd remove the scope and mounts and reset using a mild setting thread sealant on the screws. Then re-sight the gun in. If that doesn't work then either damage to the barrel and or internal damage to the scope must have occured and would require sending them back for repair/replacement. If your not comfortable doing the work a gun shop can do it and should not cost a fortune to do. Hope this helps, good luck that's a nice package you got there!
