Cutenews emoticons problem

[Lenneke15]

So I installed Cutenews yesterday, everything works fine and I'm glad, but when I deleted the emoticons from the cutenews/data/emoticons map and uploaded new ones, it didn't work. I also added the names of the emoticons in the System Configuration part in Cutenews itself, and they still don't work.
I really don't know what to do anymore as I tried everything that might solve the problem out already. I deleted the .htaccess and uploaded a blank index.html page, I re-installed Cutenews, I chmod'ed everything again to 777, but nothing works!

If you have an idea of what it might be; please let me know! It's so annoying not knowing what the problem is.
Thanks in advance!
