Want to remove a installed vB and set up again.HELP PLZ!!

[soamjena]

Hello friends,
I have a a Joomla website here, http://www.southfloridajazz.org/
And i bought a new License for vB for a forum for this Joomla site.


Then i used a Bridge and got it integrated to my Joomla site.
It was all working fine till that.
But after i installed few plugins in my vB forum via ADMIN CP of vB,the total site style got messed up and when i checked back to my forum,
http://www.southfloridajazz.org/vbulletin/index.php

Before i installed those plugins,the forum was looking so nice,as it was completely integrated to my Joomla site design,but now its back to the default style of vB forum. It was blue,but i just managed to make some colour changes to the default style files.
But really,im bored of this shit..
I really want to get my forum again integrated to my Joomla site..


Ok so here is my question,
I have installed the site here,
http://www.southfloridajazz.org/vbulletin/index.php

But since its completely messed,i want to completely remove the site at this "vbulletin" folder,and then install it again at "forum" folder. I will rename the "vbulletin" to "testvb".

So am i allowed to do this????
Kindly reply to my query.Its something urgent for me..
Help me...
