Upgrade from 1.9 to 2.2 caused problems

I tried upgrading from 1.9 to 2.2 and the database upgrades worked properly and I completed the steps for the website files but after everything finished, I get this error when I go to my main page:

Security Exception

Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Can anyone tell me how I can fix this problem?

Hmmm, seems that nopCommerce has an issue when running in medium trust. You need one of the following:
1. Run nopCommerce in full trust
2. Download source code version and apply changeset a1147f9c4dcb

I replaced the files with the new files and I'm now getting this error:

Access to the path '\\fs1-n02\stor2wc1dfw1\404408\457711\www.ooples.com\web\content\Plugins\bin\Nop.Plugin.DiscountRules.BillingCountry.dll' is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.


How can I fix this problem?

I tried the fix that you suggested and I received the following error:

Andrei,

Can you please review my post (the one before this) and give me some feedback?  I'd really appreciate any assistance you can give me on my performance problems.

I'm kind of stuck here!

thanks!

I tried running the changeset but it won't let me build the project because it says my version of Visual Studio 2010 Professional can't open the project for Nop.Web and Nop.Admin

Do I need an extra sdk or something similar to open these projects? What am I missing?
