Форуми / Cotonti / Support / Links are not working correct

I have a problem on my website. The bbcode for urls is not working correctly as how it should.
I checked it on this site and here it is working just fine as you can see below.
The problem is with links like these:

http://community.bistudio.com/wiki/ArmA2:_Moves

The ":" makes the bbcode being unable to paste the link correctly. If you use bbcodes the output looks like this:

- [url=http://community.bistudio.com/wiki/ArmA2:_Moves]Animation list 3[/url]
- [url]http://community.bistudio.com/wiki/ArmA2:_Moves[/url]

While if I post these links here they are pasted correctly:
- Animation list 3
- [url]http://community.bistudio.com/wiki/ArmA2:_Moves[/url] <----hmmm, seems not to work here neither?

You can have a look for yourself how it looks in the forums:

This is my bbcode:

\[url=((?:http://|https://|ftp://)?[^\s"':\[]+)\](.+?)\[/url\]

with html:

<a href="$1" target="_blank">$2</a>

And here is the other bbcode:

\[url\]((?:http://|https://|ftp://)?[^\s"':]+)\[/url\]

with html:

<a href="$1" target="_blank">$1</a>

Anyone able to see what is wrong?
