Historical data error in NT 7

[Trevor.Richter]

I have been trying to import historical tick data for ES, from 1998-2009. I had these data working perfectly on NT 6.5, but in NT 7, the data from 2004-2008 fail to import.

I have tried the following, none of which has worked:
Reset the DB -- no help
Repair the DB -- no help
Restart NT -- no help
Restart computer -- no help
Unzip and reimport ES data -- message says "imported successfully", but problem persists

Here is the log entry:
ES 12-09: Volume in line 0 is invalid since it is <= 0. This line and subsequent invalid volume lines have been modified and replaced by a value of 1.

The problem seems to be only for ES, as my other instruments have been imported correctly.

Any ideas??
