FlexTestDrive-Unable to invoke CFC - Error Executing Database Query Java Exception Error

Hi,

I just started ramping on Flex and CF. 

I was working through the FlexTestDrive but am getting stuck at the same place on two different machines using WinXP, IE8, CF9 and FB 4.5 on a laptop and WinXP, IE8, CF10 and FB4.5 on a desktop.

Up to the point where I am adding data to the db provided by Adobe everything works fine.

Module 2 - Add Data

I get an error popup that says:

Unable to invoke CFC - Error Executing Database Query.

Java exception: 'Negative position: java.lang.IllegalArgumentException'.

Has anybody reached that position and had this issue.

Couldn't find anything similar on the forums or on Google.

Thanks.
