I thing is, i was just trying to send IOTA to bitfinex, i didnt receive nothing is this adress for months.
So did you initiate that above mentioned transaction ? Without more details it's hard to help

Sorry i tried to figure out for myself but i need help.
I have a old adress, that i received 73 days ago exactly 1.12723 Gi from bitfinex:
https://iotasear.ch/address/BOTBWRELVGUDEWHUFJKFMCFIYQF9P9HLOAO9VYCSPQMTKGKOUZZXAXWSQZKGLEQFB9QVHJXVMUWXTFM9WI thought that today my iotas was stolen but now i dont know what happened.
The missing fund is exactly 1.12723Gi, but i had a little more iotas and only exactly 1.12723Gi gone...maybe is some problem with transition process.
Some days ago, i tried to open my desktop wallet and it cant connect, so i download a newer version but showed me 0 iotas.
This was not the first time that happened, last time i was able to recover balance by rettaching new address some times. So this time i tried it and didnt work. Tried to using reclaim tool too, but i am not sure what i did but didnt work too.
So i tried to rettach again more times and my balance appeared, i thought that was everything all right, but when i tried to send iotas i got KEY REUSE error.
And finally, some hours ago i saw in my wallet history a transaction sending exactly 1.12723Gi to another address that i dont know.
And now i dont know where is my 1.12723G.
what should I do?
Tks
