Well I deleted the bitcoin app support folder, bitcoin app folder, installed it again, opened it, had a new address, closed it, copied wallet to app support, opened it, it was mine and it said there was a pending deposit but it had made a new address and when I tried to change addresses it crashed. Whenever I open my addresses and click on one it crashes.
Don't worry it makes new addresses all the time. It keeps the old ones too. Do it again and leave it alone this time.
Bitcoin *demands* that one learns patience. 8^)
