How to fix Nikon Error Press Shutter Release Button Again DSLR

If you own a DSLR and suddenly an error of 'Press Shutter Release Again' pops up and it wont take any pictures although you press the Shutter repeateDly,what would you do? I had this problem a week ago on a vacation using my 1st beginner's DSLR ,a Nikon D3100. This can easily happen if you drop your cam too If its under Nikon Warranty,you can turn in to the dealer & wait for the repair but what if its beyond warranty period, or you bought it used with expired Warranty? Here's my solution to fix it to save some repair charges and guess it might bless someone with the same problem there. Theres a small hinge thats blocking the shutter to release ,press it through and it should be fine :)
