hmm.. dm, i got this message (session problem) on my localhost too. i dont really now what it means. But there's a link below this message. When i followed this link.. it has worked.
It cannot be a problem with vBindex.. cause the vbindex-script just reads the latest poll in the pollforum. nothing more. the action of voting.. has nothing to do with it.
ehm.. when you cannot fix it anyway.. contact a mod or a dev or just ask somebody who could help you
