So i wanted to trade in my BTC for a gift card, so i withdrew all my coins to my receiving adress. Then i open up bitcoin.exe and it shows that my address for receiving coins is completely different, i researched it a little and found out that it changes and that i should be able to see my old address in my receiving address list. Well i formatted my computer a month ago, but im still using the same .exe as before, and now when i check my receiving address list my old address (that i use with bitcoin market and deepbit) isnt even in teh list, did i just loose all of my BTC or is there a way to access my old address?
