[Problem]Need some help with connectivity

Alright, so heres the problem. My client no longer connects to my server...

reason? I have no clue but my theory would be that i deleted something important, why would i think that?

well because recently i removed over 130 files, and over 20 programs. But heres the thing, non of the files were not in my client/server folders, so why?

to be sure, i reinstalled my client, and still nothing.

does anyone have any idea what the problem could?

-I double checked my ports, they're still open, i double checked the ip, the cidserver.dat-

I've had this happen to be, but it was because my LAN server ip changed and I just needed to modify my port-forwards... but you say you've already checked if they're still open, so, I dunno.

took a third look at it, it was the problem, i missed one changed digit in the lan.

appreciate the help infamous, hope i can return the favor one day.
