Cant login or register after succesfull installation

Hi all!

I'm using nop3.10, i downloaded the source and run the two .bat without any modification on the source code, and uploaded the deployable folder.
The instalation went fine, but when i try to login, or register i get the same error.

Using: .NET FW 4.5, sqlexpress2012, windows server 2008.

Has anyone any idea why?

Thanks for your help.

OK.

If anyone get this msg, just instert the following line in the web.config, under the system.web element

<machineKey validationKey="AutoGenerate,IsolateApps" decryptionKey="AutoGenerate,IsolateApps" validation="HMACSHA256" decryption="Auto" compatibilityMode="Framework20SP1" dataProtectorType="" applicationName="" />
    <browserCaps configSource="browserCaps.config" />

I dont know why its solving the problem, but its helped me :)
