Hello, I have the RadSessionPageStateCompression enabled on my site, however I keep getting these errors since upgrading to 2010 Q1:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. However, I don't use a Web Farm and my machine key and validation key are properly defined in the web.config. What could be the probable cause?? I am using Session State to store some info of the user and FormsAuthentication (i don't now if that has something to do but with my problem)... The IIS version I am using is 6.0 and .net Framework 3.5 SP1. I also have radcompression postbackcompression enabled and my viewstate encryption mode is set to "Auto".
Thank you in advance,
Manuel
PS: I also generate my radgrids dynamically on page init.

Hello Manuel,
I'm afraid that I'm unable to recreate the described behavior locally, therefore it will be appreciated if you can provide more details about the exact scenario in which you are getting this error.
Regarding your other question. I'm afraid that support options are aplicable only for inquiries submited through our support ticketing system and not for such posted on the forums as stated here. Also you may refer to this blog post about few tips on getting the best out of Telerik support.
All the best,
Rosen
