Is this fold ever profitable at the low limits?

I had only been at the table for a couple orbits. Normally, I would check, call this river but I really want to tweak those extra leaks so I decided to go with the bet/fold rather than check/call or bet/call (I normally don't ever fold this river in such a large pot). However, with only a few hands on the villian in PT, I made this fold because they seemed solid, at least that is what I got from this previous hand:

At these limits, is my play of folding a mediocre hand in a 13BB pot for one bet in the first hand ever really profitable at these limits?

P.S. I am new to using the converter, but can anyone tell me how to get rid of [color=#CC3333]? Someone told me to use a text editor to change all the = signs to : If this is true, can you also recommend a good text editor to use [img]/images/graemlins/smile.gif[/img]
