To get the massage oil in the 0.8.2v, you need to go and see Amy at the gym, she will say no at 1st, talk to her again and offer her Veronica's panties, then she will get the oil for you...the only problem you have is that you have progressed so far with the other characters that you have missed a few hints and possibly bypassed the trigger for that event...as for your 'edit' you don't meet Linda 'with' Cassie, you have to talk her into letting you go up to Claires office, you will meet Linda there. Anyway you can try both solutions hopefully they will work for you. Good luck.
