Hm, I'm sorry, I have the German and the UK/US version - so, I don't know which version the Australian is. I gather this => you didn't patch to the AUSTRALIAN version 1.45? Please, try it. DON'T patch with the UK/US version, you will have probs, as your Starforce protection version is different.
After you have patched => please go the billboard in the Black Temple or leave the town and reenter => did you meet her there? If not, try it after the patch again. If you met her - then go to the west entrance of the crypt, shoudl be open then. She challenges you to a duel.
