Hi, I think the table in the Level 2 Capstone Project may be corrupted as it is missing a sym file and I'm not sure how to proceed. Any advice or capability to reset the workspace to regenerate the table would be greatly appreciated. James

Hi Megan,

The workspace has three tables nbbo, spread and trade.

I can only access the meta of spread so I think it has affected both nbbo and trade tables.

I would recommend running:

```
delete nbbo from `.
```

This will remove the table from memory and to reload the table run your code from exercise 1.1 again.

Let me know if you have any questions about this!

Thank you for the fast reply,

I've attempted the command you gave for both nbbo and trade, but the issue appears to be persisting. I think the issue might involve

key hsym `$getenv[`HOME],"/fundamentals\_capstone\_dbs"

returning

```
`s#`2020.08.03`2020.08.04`2020.08.05`2020.08.06
```

and not including sym, as meta nbbo returns ..sym, but I'm not sure.

Hi @jamesthompson&nbsp;

Are you still experiencing this issue? If so, can I access your server to take a closer look?

Thanks!

Hi @silviamat ,

This can happen on individual servers if your data gets corrupted. If you try removing the tables from memory and then re-running the code from the start e.g.

delete nbbo from `.

Let me know if you’re still having issues and I can access your server and reset it for you

Thanks,

Laura

Hi @lkerr2 , thanks for the quick reply!  
I have tried that as I saw it suggested in the conversation above, but I’m still having the same issue, so please do access the service if you can.

Thank you!

Hi @silviamat can you make sure you’ve saved all your code locally and then let me know when you’ve done that and I’ll reset your workspace. Otherwise you might lose your progress.

Thanks,

Laura
