Run the program in olly, press okay when the message box comes up, go in the dump and search for "Post". I did it the uber cheap way, I didn't actually decrypt anything.
I'm not good at reversing decrypted stuff.

Haha, but you did do it, but if I tweak a few things that wouldn't be possible anymore... hmm, I'd just crypt the message agai

No matter what way you encrypt it, if the original string is hardcoded inside the program it will be easily visible.
maybe the program should decrypt a message and hide the new message somewhere. idk...
maybe you could also write IN you code a string as a char in ASCII codes but with 0x01 added and everytime you proof it or so you decrease the value by 0x01 again ?
Example:
described code:
set a char to (in ASCII/hexadezimal):
54\44\49\50\4E
T D I J N
then you got a function which takes everysingle number of the char and subtracts 0x01 from it so it looks like this
53\43\48\49\4D
S C H I M
and it returns the new char
now you made from your TDIJN -> SCHIM
OK now I've made a little programm for you ;-)
1.You have to enter a word -> When it's the right word it'll say this to you and you have
2. Post the word here (Be carefull with BIG and small letters (c or C))
Eh?

Is that a real error or a decoy? Olly seems to have problems opening it aswell.
Here's the application event log if you need it:
