Error Calling SQLCLR UDF

Running SQL Dev Edition on Win2K3 Enterprise Edition. I get the following error.

Msg 6522, Level 16, State 2, Line 2

A .NET Framework error occurred during execution of user defined routine or aggregate 'AddressCorrect':

System.DllNotFoundException: Unable to load DLL 'D:CorrectA.dll': Not enough storage is available to process

this command. (Exception from HRESULT: 0x80070008)

System.DllNotFoundException:

at UserDefinedFunctions.CorrectA(String query, String sentlen, StringBuilder errcode, StringBuilder FirmName, StringBuilder urbanization, StringBuilder Dline1, StringBuilder Dline2, StringBuilder LastLine, StringBuilder Stringaddress, StringBuilder DPC, StringBuilder Checkdigit, StringBuilder cityname, StringBuilder stcode, StringBuilder zip, StringBuilder addon, StringBuilder croute, StringBuilder LACS, StringBuilder LOTsequence, StringBuilder LOTcode, StringBuilder PMB, StringBuilder results, StringBuilder strnum, StringBuilder secname, StringBuilder secnum, StringBuilder countyname, StringBuilder countynum)

at UserDefinedFunctions.AddressCorrect(String inputAddress)

Box has 2GB Ram, with no other processes runing, cant understand why it says out of memory.

Appreciate any insights.

Thanks,
