I used the method for rooting an unlocked desire, with a gold card.
I got almost to the end, up to the step;

"In the command prompt/terminal window, enter either 'step2-windows.bat', './step2-mac.sh' or './step2-linux.sh' as appropriate"

However, my zip i downloaded didnt contain "'step2-windows.bat'"
which now has lead me to a problem where i am stuck on the 'recovery' screen.

Please can anyone help me, im afraid ive bricked my phone

I'm far from a expert, did you follow these instructions?

How to flash ROM

1. You need to have HTC Sync and Android SDK installed
2. Download this
3. Turn off Desire and then turn it on while holding back button to enter bootloader(white screen)
4. Once in "white screen" press power button again to enter bootloader
5. Connect Desire with PC
6. Press Volume Down and than Power to enter Recovery
7. Now the red triangle should show up, go to folder you downloaded file and press recovery-windows.bat, recovery-mac.sh or recovery-linux.sh depending on which OS you have
8. Now you are in recovery mode (green screen), press Wipe and than Wipe data/clear storage, than press optical tracker to confirm it
9. After that press Volume Down to go back to main menu in recovery
10. Navigate to Flash zip from sdcard using optical tracker, select .zip confirm it and wait until process finish, after that press Reboot system and unplug you Desire

the file is included in one of the files you would have already downloaded - you just double click it when told to in the guide. Sorry I can't remember where exactly, I've downloaded and extracted so many files in the last 48 hours. All has worked pain free to be fair though.

Sure somebody with more experience will be along to help you out soon.
