Update old K-Relay plugins?

I'm relatively inexperienced when it comes to compiling or writing C# so I need a little help.

How difficult would it be to update PixelZerg's ROTMG Trade bot?
The source is released for it.
It's about a year and four months old.

I don't know if this will be a relatively mundane task or a challenging undertaking.
Help would be nice! Thanks!

Deca has done a lot of updates, so you might need to compare the last client it was made on and the current one to add any changes (a lot!) that have occurred.

It is not similar to updating a client. I don't know the details to it, but I'm guessing you just need to change the pointers and add new assets.
