It is kind of hard to tell what the issue is with out seeing the code. Have you been changing/adding inline styles to that page recently?

If consistent and frequent, likely a web farm/machine key issue (http://blog.aproductofsociety.org/?p=11).
If infrequent, it may be a by-product of a spider or crawler accessing the site with a cached version of a page in which the .axd has expired - the decryption key is invalidated, and that's what is throwing the error (http://forums.asp.net/t/1019434.aspx).

I do not know what "inline styles are so I have to say no to that. Yes these are consistant errors a bunch of them seem to be generated, often at night.No one is on the site.

"a bunch of them seem to be generated, often at night" makes me think it is a spider indexing your site. Add an exclusion to your robots.txt files like so:

User-agent: *
Disallow: /*.axd$

[Chris Hadden]

Don't I want spiders indexing my site?

[afm]

Yes. But not the *.axd URL's. Those URL's do not point to content, but things like javascript or CSS.
