Could that have such a huge effect to knock out that one channel?

Yes, WGEN is on real channel 45, which is a UHF channel. UHF signals are affected by trees more than VHF signals. See attachment.
WGEN is also your weakest signal in Green, and in a different direction.

The antenna is currently not grounded, would that affect the signal and make it worse?

Sometimes when the coax shield is grounded, it is better able to reject interference that might harm a weaker signal.

Is my antenna appropriate for my distance to the towers?

Distance ratings for antennas are a creation of marketing departments. We don't pay much attention to them. What good is a 60 mile antenna if you are behind a mountain that is only 5 miles away?
We look at the signal path and the Noise Margin. Your report says that WGEN is LOS (good) and has a NM of 35.7 dB (also good), which means it is that much stronger than the minimum necessary for reception.
Your antenna is appropriate for the signals listed on your report and the channels you want.
Keep in mind that your tvfool report doesn't take into consideration trees or buildings in the signal path, and assumes that your antenna is outside and in the clear.

Could it be that the antenna is just a old (it's about 2 or 3 years old),

It is possible that connections can deteriorate with an outdoor antenna system. Have you ever been able to receive WGEN?
How many TVs are you feeding, and how long are the wire runs? Where is the amp located?
You have two strong local FM signals that
might affect TV reception. If they do, you can insert an FM filter in the coax line. See attachment 2.

If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.
