Datagrid datasource binding error

[=?Utf-8?B?cGpzaW1vbg==?=]

I get the following error:

Unhandled Exception, Log_Id does not belong to table Queue

.... when I execute the following code ("dgQueue" is my datagrid control):

Dim dtQueue As DataTable = gclsDataLayer.GetQueue()
dgQueue.DataSource = Nothing
dgQueue.SetDataBinding(dtQueue, "")
dgQueue.Refresh()

I get the error on the SetDataBinding call. The above code lives in a
Function that is called every one minute (by using a Timer control). The
first couple of times through the Function, I don't get the error. After a
10-30 times, I'll get the error. When the exception is thrown, I check the
contents of the dtQueue DataTable, and the column does, in fact, exist! I
put a try catch around the call, and I can't catch the exception!

If you don't know the solution to the datagrid issue, could you provide some
assistance in catching this exception? As a last resort I could jsut catch
and swallow the exception, but right now I can't seem to even catch it.

Thanks guys!
