chromatic aberation ruining the fun :( Can anyone help?

Dear DPR ^^

I have no idea wether this is the correct forum to ask this sort of question. But i'll try

I took the following shot from Pienza in Italy at sun down. I think it turned out pretty good. I'm in the process of making a calender for my in-laws as a crissy present from me and my girlfriend. using pictures we've taken over the years. (Full image and crop of the problem is attached)

However, I am no shark with photoshop, I have already gone over it in CameraRaw with the adjustments i felt necesary. And also the patch tool. But i really really can't seem to be rid of the chromatic aberation in the lower right hand corner, especially visible on the trees. Any of you guys have a suggestion to how i might fix this? Or improvements overall, all suggestions are highly appreciated again, i'm no PS pro, so helpful tips and advice is always welcome.

I might have been a wee overzealous with the clarity slider in CameraRaw, which might have exacerbaten the problem?

Oh and just FYI, i have the original file in .RAW format, so most anything can be done to it. The file i'm attaching to this is the image processed thus far.
