User Unable To Save/Open Report In Report Builder

Hi,

I have environment that use SSRS 2005 ad hoc reporting.

One of the users (out of 200) is unable to open or save reports in the report builder.

the user succeed to open the report builder, when he try to save report that he build from shema he get error. as well when he try to open an existing report that build in the report builder he also get an error,

On open the error is:

The numeric portion of 2pt cannot be parsed as a unit of the type point.

The Initilizer for 'Microsoft.ReportingServices.Design.Constants' threw an exception

On Save the error is:

System.IO.StreamReader: Deserialization failed: The type initializer for 'Microsoft.ReportingServices.Design.Constants' threw an exception. Line 2, position 2

Please note that I succeed with second user to create ad hoc report on the first user

computer. I also failed to with the first user to create ad hoc on another computer.

It seems like permissions issue

Thanks,

Assaf
