I'm trying to set up my x50v to store message attachments on my SD card. I've read through the Axim threads on the methods to have attachments stored on SD or CF instead of BIS by using either Tweaks2K or editing the registry. Here's my problem:

When I go to the Storage tab in Messaging, it says "Storage Card (not installed)". Yet, in file explorer I can see the BIS and SD contents, folders and files just fine and I have apps running perfectly from both locations. When I check the box, "Store attachments on storage card", the Axim remains stuck on that page, doing nothing when I hit "ok" or attempting to move off the Storage tab. When I uncheck the box, the Axim lets me navigate again.

I've done a soft reset and tried again. Made no difference. Any suggestions?
