CR for VS2010 - Error: TypeInitializationException: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception.

Hi all. I'm new in the forums and I would like to ask you for help about a problem I'm having with Crystal Reports for a week.

I'm using Crystal Reports for VS2010 in a 64 bits machine. Reports work ok. When uploading the ASP.NET Project to a shared server (64 bits as well), it fails:

Retrieving the COM class factory for component with CLSID {4DB2E2BB-78E6-4AEA-BEFB-FDAAB610FD1B} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

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. 

Exception Details: System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {4DB2E2BB-78E6-4AEA-BEFB-FDAAB610FD1B} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)). 

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 File 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.

The technical support of the hosting say me that several projects using CR are hosted in the same server as mine. 

Anyone could give me a clue?

Thanks in advance.
