Your daughter seems absolutely fine with receiving money and gifts from you, but not responding so, if it was me, I'd stop the money and gifts and just send cards!
That way you're still offering your love, but saying you're fed up of being used!!
You could ask the other 2 daughters and your sister round for a meal or drinks, all together, THEN ask them outright what is going on, why she's doing this and why she won't just tell you herself? They know something you don't and it could possibly be something huge that you didn't realise affected her, or something really small that you overlooked as meaning a great deal to her!
I am assuming you didn't just up and move when you did, and that you had discussed the move with your daughters, so I really can't see that being the issue unless she wishes she had spoken up at the time!
Please let us know how things go.
