RED "MENU?" error on top screen, it was working fine today and all of a sudden..

:( Hello, I downloaded a bunch of games onto my 4gb card, it was working and everything and then i turned it on and it's giving me the message "MENU?" in red on the top screen. Can you PLEASE help me? Thank you soooooooo much!!! i don't know much, but i followed a friends instructions and it worked perfectly, now....not so much.

What flash card is it?

What card is it, what size micro sd?It usually means the menu files are missing, just copy them onto it. Else copy everything onto your computer, format with Panasonic Formatter and try again.

Re: RED \"MENU?\" error on top screen, it was working fine today and all of a sudden..Awww...what a quick reply - thank you so kindly! :)
It is an R4 card with a 4gb micro SD card inside made by kingston.
I had games on it and it was working fine, then today i went to add more games and delete others...tested some games out. It was working fine then went to turn it on again after 15min and it showed this errir all of a sudden. i know nothing about this technology stuff, all i know is that it isn't working. :( Boooooo!!!!
If you could help me, that would be totally Awesome.

I just don't get it.....it was working from 11:30am until about 1pm.
Then - Nothing....just this silly error.
I don't know how to reformat anything.
I did this @ school this morning and I have a ocmputer at home, but no internet, just on my work computer, but im afraid i don't think i can download of insert a USB card/flash drive.

If it is an original R4, the 4GB card will not work on it. You have to use 2GB or smaller.

I rec'd purchase this R4 in August. It came with a 2G and that worked fine. Then in October, I purchased a larger card (4GB) from the same company (my sister did the same thing and she has never rec'd this problem) It was working great from October until now. I downloaded more gmaes today and i was able to play the new games, I shut it down and reached for it to lay and it now says MENU?.

Does your computer recognize the MicroSD when you connect it?You may have accidentally deleted the firmware files from the card. You need to go to the website listed on the box to download the correct firmware files. Or www.linfoxdomain.com/ds and download the ones for your card (not any other card).

Re: RED \"MENU?\" error on top screen, it was working fine today and all of a sudden..I will make an attempt all though I am not savvy when it comes to downloaded and uploading etc.... i don't even know terms. But do you know why it was working perfectly this morning for a couple of hours and know nothing????
Doe this mean I lost all of the games I downloaded???? Will I lose any in this process??? and what exactly do i do??? thank you thank you thank you!!
