Uh, it sounds like you may have a pirated/warez version of UBB which is a no no. The ONLY way to get a UBB is directly from Infopop by buying a license.
If you have a valid UBB license, you can get the latest UBB (and this is the ONLY place you can get a UBB) by going to the Infopop
Member Area If you don't have a valid license, but wish to use a UBB, then go
here to purchase your UBB.
When you download your valid UBB zip file directly from Infopop, instructions will be included on installing the product.
And as a side note, if you didn't get your UBB through legal means, you may consider passing on the info about how and where you got it so Infopop can investigate. Just email Infopop at
piracy@infopop.com.
