WRT610N DHCP Reservation Client Table empty, please help!

Question

Even though there are about 15 devices connected to the router right now there is literally nothing showing up in the DHCP Reservation list, and when I add something manually it will not come up either. I have tried reinstalling the firmware and even setting the options to default. Has anyone had this problem before? I have checked the forms and saw nothing on this subject.
This has been an issue since I bought the device, however the DHCP list did show up a couple of times when reinstalling the firmware but would go away after ~20 minutes of ussage. Any help would be greatly appreciated!

Surprise surprise.  After being explict with Tech Support, having them repeatedly confirm that someone will be calling me today, I got nothing.  There was not a peep whatsoever from them.  I guess I kind of suspected that since they had done all that they could think of to resolve the problem yesterday.  I'm just another disgruntled customer to them.
Hence, I took matters into my own hands to get my DHCP Reservation list back and to prevent it from disappearing in the future.  I also took some very good advise from chrizburnz.  The steps provided below are exhaustive and probably 50% unnecessary.  The problem is knowing which steps are crucial and which are redundant and/or needless.  I wasn't going to waste any more time trying to figure this out.  I spent hours with Tech Support (3 different techies altogether) and they couldn't get my list back, even after reinstalling the firmware.  I don't plan to be updating this list a lot anyway.
To get your DHCP Reservation list back and keep it from disappearing in the future, do the following...
Power down all LAN and wireless devices that connect or want to connect to your router with the exception of a single wired computer.
Save your current router configuration.   There is a Backup Configurations button on the Administration tab.
Hit and hold the reset button on the back of your router for 30 seconds as previously advised.
After releasing the button, pull the power cable out of the router and wait another 30 seconds or so.
Plug the power cable back in and wait for your router to boot.
Load the original CD that came with the router and redo the Setup procedure.
Once the router pulls down an IP address from your modem, you can then start to configure your DHCP Reservations list from scratch.
Click DHCP Reservation off of the Setup --> Basic Setup tab.
Starting with the PC already connected, enter in your current PC information using the Manual method.  Don't use the Add Clients button.  (The MAC address should be appearing in the list above this button.  You can just cut/paste it in.)
For the name, do not use special characters, spaces, or numbers.  Just use upper/lower case letters and keep the name short.
Click Save Settings.  Click Continue.  Click the Close button at the bottom of the window.
Click Backup Configurations on the Administration tab.  (You can always restore if your list vanishes on you.  You don't want to have to start over from scratch the next time.  You can just do the restore.)
Power up the next device.  They appear to pop up immediately in the clients table.  At this point, the DHCP Client table should be functioning as expected/advertised.
Repeat steps 9 through 14 until all your devices are full reserved.
Again, this is the exhaustive procedure.  I can't say which steps are crucial.  Just add one entry at a time, short names, letters only, and save the configuration each time you successfully add an entry.  (Never "x" out the DHCP Reservation window.  Use the Close button.)
If anyone finds out the real deal here, can you please post it.  Or, better yet, Cisco can fix their firmware bug in the next release.
