Removed memory card from camera

Question

Hi Ginko! I really goofed this time. I have a Nikon Coolpix 4 and removed the memory card with the power on. Will a new memory card fix the problem? I am getting a message of corrupted picture files for the recent photos when I try to unload images to my PC. Please advise and thank you so much!

Sincerely,
