cannot purchase a secure certificate because of different secure bit length.

I am trying to renew the secure certificate for a IIS 5 website running on a WIN2K3 server.  The "Bit Length" being used is 1024.  When I purchase the certificate, it looks like it is asking for a 2048 cerreq.txt.  Is there a work around for that?  

The 1024 bit length site is live in production.  

Please advise.

    creating a 2048 bit cert request is recommended - 1024 is considered breakable these days (of course, you may not feel someone would waste the money on breaking *your* key, but as a matter of policy, most CAs no longer accept keys below 1536)

    I know.  The thing here is the current certificate was created using a 1024 bit length.  When I renew, it generates a 1024 bit length cert request file which is not being acceptable by the SSL vendor.

    Is there a way to change the existing 1024 webite to 2048?

    @nav: website doesn't need changing, just generate and use a *new* 2048 bit certificate for your existing website, it will work fine.  Your only issue is the attempt to re-use the existing 1024 bit CSR, rather than create a new one :)
