No problem... I thought I would like that option turned on, since I store all my program installers on the memory card (don't need activesync that way), and since I usually just want to access the storage card from the PC when it is plugged in. But I've been doing a lot of testing lately and have needed it in ActiveSync mode far more than I expected for reg edits and access to the Windows folder.
Anyway, just download the package you prefer again, and it'll be fine this time.
