Annoying SQL Error Msg - INTRA-QUERY

Hi,

Pbbly most of you know this:

Intra-query parallelism caused your server command (process ID #57) to deadlock. Rerun the query without intra-query parallelism by using the query hint option (maxdop 1).

I've seen MS KnowledgeBase for that (http://support.microsoft.com/default.aspx?scid=kb;EN-US;837983)

But I have some probs with it:
1. I don't have permissions for this kind of queries
"USE master
EXEC sp_configure 'show advanced option', '1'
RECONFIGURE WITH OVERRIDE
GO"
2. I don't know what is an "intra-query parallelism"...

I'm attaching the query I use. The query runs OK for some parameters but gets this error msg on other parameters.

I'm using a single CPU on 2003 STD Edition.

Query:

create table #mytemp_table
(client_id int not null, commission_value int null)
insert into #mytemp_table (client_id, commission_value)
select client_id, sum(transfer_value) from users_transfers where transfer_type in (1,3) and is_paid = 1 group by client_id

select
u.name [Vendor],
u.email,
sum(cost) as Payment,
cmpd.vendor_id,
ua.name [Agent],
vd.join_date,
commission_value [paid],
allow_sign
