Try this if you haven't already. Once you get an unlock, click on the "unlock firmware" button in pv2tool. This will make it permanently unlocked.

I made that change to the directory, and that did the trick. Thank you. Do you have any other recommendations about the image quality enhancements? Also, is there a limit to the number of picture that I can take. I took 3 pics, deleted them, and then took a couple more, and I noticed that the count continue to increase. I think I remember reading before that there was a limit, any thoughts? Thanks

I dont think there is a limit of how many times you can use your camera(picture wise) but there is a 25 picture limit on the camera at one time.

Yes, the directory change did it. Thanks to all.

HELP NOT AGAIN! Again, I cannot read the camera. What the hell is going on? I didn;t change anything. I am using PV2Tool 2 like always. I hit "open camera" then "unlock." Then I get the following message, ** External key file, pv2keys.txt was found and will be loaded PV2Tool 2.14 Use this software at your own risk.

Who knows whats going on. Just for the hell of it, I tried one more time and it worked! So I hit "unlock firmware" this time. Does this mean, I just have to hit open then download raws?

you might have a iffy connection to your camera

On a 410 6600 I get a challenge that before reformatting is 6 lines each line having 32 characters (not counting spaces). I've tried making it three lines each with 64 characters but that didn't work. Any ideas?
