Problem upgrading to 2.3? HELP please

[chunkylover]

I was upgrading my Samsung Galaxy Mini (S5570) from 2.2 to 2.3 using Kies. It was going fine until I got a message saying that it Failed. Then It asked to do Emergency Recovery Mode. I did that and then my phone is stuck with the image of a computer and cell phone with an exclamation hazard sign. I tried doing the Troubleshooting Error on Kies, uninstalled then re-installed Kies, but I cant do anything now. Please tell me what to do???
