For future reference, it would be immensely helpful if you could attach said error message with your posts, instead of just saying that there is an error. Without actually seeing the error, it's hard to arrive at any conclusion. That being said, are you sure DBI is installed? If so, does DBI currently work for any other scripts? Did it work at one point and just stop all of the sudden? With a bit more information, I'm sure we can be of assistance to you.
