good luck finding a way. i did the same thing you did so i went and used boot camp to delete the partition and start over, but it gave me an error when i went to repartition it saying i had to reformat the drive completely before boot camp would partition the drive again. anyway, i did it then it worked fine. as far as your problem, there is an app that i found a week or two are thats suposed to be able to resize partitions on the fly but as usual with me.. it didnt work, and its 3am so i cant remember the name of the app
