Can anyone help solve this issue please? As you can see even the maximum fee results in failure.

edit: After submitting, it goes through all confirmatons, but really nothing happened and I get an error.

edit2: ok I'm worried now. Its not sending it to the address I want it to??

I want to sent it to 0xf9e8c379b32b269951fbbe08dc12ce4447b881b3 but 2 times its gone to 0x48c80F1f4D53D5951e5D5438B54Cba84f29F32a5 I dont know what the hell address that is, but I didn't paste it. I'm using Ethereum wallet.
