CREATE ASSEMBLY - EXCEPTION_ACCESS_VIOLATION

Question

I am trying to create an assembly on my SQL Server 2005 server. Here is what I am using:

CREATE ASSEMBLY [SQLCLRTest]
    AUTHORIZATION [dbo]
    FROM 'path\to\my\file.dll'
    WITH PERMISSION_SET = EXTERNAL_ACCESS;

I am getting this error as ouput:

Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.

When I look at my error logs I find the following in the stack trace:

Exception Log -  EXCEPTION_ACCESS_VIOLATION

I've been Googling around and the only solution I have seen to this is to change the database owner, which is not an option for me. I'm thinking that I need to have some sort of permissions set for my user but I can't find exactly what I need.

Could anyone give me some advice on how to handle this? It would be very much appreciated.

Thanks!
