Error launching Lord of the Rings Online

Greetings!
I can’t launch my Lord of the Rings Online (LotRO), can someone help me with this? I recently reinstalled LotRO, but every time I open the launcher it crashes and posts a long error message.
I don’t know what to do, and I’m hoping someone can guide me.

I will be forever in your debt if you help me out.
Thank you!
