Dell Streak 7 SD Card problem?

[Guest GB-UK]

Since the update to honeycomb I cannot see any files on the external SD card. I can go into setting and storage and it see's the card but when I use a file manager to go to the card it says there are no files on the card. It previously had no problem seeing the files before the update. It has PDF's and some AVI files on. Anyone got any ideas how to fix this?

Would have posted in the Streak 7 forum but it won't let me start a new topic for some reason!
