Cant allocate space for object

Hi!
I'm running mssql 6.5 and I've got a problem with a pretty basic errormessage. I've managed this scenario before, but I't doesnt seem to work this time...
The message is:

Can't allocate space for object '-482' in database 'tempdb' because the 'system' segment is full. If you ran out of space in Syslogs, dump the transaction log. Otherwise, use ALTER DATABASE or sp_extendsegment to increase the size of the segment. (Message

What I've done so far is:
dump transaction tempdb with truncate_only
Dump master ...
I've expanded the tempdb device (alter database)

Now I'm starting to run out of ideas...
What's this '-482' (I've also got an error on -386 once)
Anybody have any idea what to do next?

Thanks!!That is the ObjectId of the table in the database.

Cannot run apparently successful installation of SQL Server Express

I am completely new to SQL Server, and have downloaded and installed Visual Web Developer and Visual Basic Express without problems
I have downloaded SQL Server Express and cannot figure how to start it up! SQL Server Management Studio Express CTP does nothing when I try to run it.

No doubt this is a very simple error or series of errors by me, but I would appreciate help.

Many thanks.

I am assuming you are installed it with default value, where express would be installed as instance sqlexpress.

1. Did you see express in Obj Explorer of MS Express ("<machine-name>\SQLEXPRESS") ? If so you could just right click on that node -> Start.

2. Alternatively, try to start it from command line by:

net start mssql$sqlexpress

|||Many thanks for your help Hungfu. I am trying your solutions which report back that SQLSever Express is running. I suspect my remaining problems are related to the CTP version!
