Hi Michelle. Sorry to hear you are having problems with your IOTA wallet.
Some questions first: You said "password" did you mean "seed" (which works as a password and should be many many letters long- I think it is 81 letters long and will have a number 9 in there somewhere )
Secondly - how did you store it? - do you type it in or copy and paste it?
Just to reassure you - if you have the "old seed password" then your IOTA are still there on the tangle and not lost. Only if you lose your "seed password" are then lost.
OK get back to me ASAP with that info and then we can go from there.
