Does this also apply to Windows where a testnet3 flag is used in the confit file? Trying to run Multibit on Testnet3 and it's not synching

I don't even know how to uninstall multi bit on my Mac. Multibit help is totally useless, it just sends me to a page that tells me about port numbers and then says but you don't need to worry about port numbers and thats it.

Thanks mate, your original answer did solve my problem, however as i said i was unable to navigate to the directory i needed as Mac Os hides the user library files, once i figured out how to see that it was fine, thank you very much.

@sdeath That's out of scope of this question. You can ask a new question about it.

Was the error something along the lines of `Unable to load blockchain "***\AppData\Roaming\MultiBit\multibit.spvchain"`?
