So, I've managed to get the UBTC into the Electrum wallet I downloaded off their website...
I input my seed and in popped all the coins... Green ticks next to them once they were recognised as OK by the network....All good so far...
Then when I tried to send to
www.btctrade.im it comes up with a message error
"the transaction was rejected by network rules. \n\nMissing inputs\n" then a whole lot of numbers following that...
Is there anything I can do? Or anything I am doing wrong?
Do I need to download the 150gb wallet to be able to send them?
How do I get them out of the Electrum wallet?

Same problem as you electrum shows balance of 1.3 UBTC but can spend with same error
, I emailed support with address balances in question. I see zero UBTC on the block explorer, but before I imported keys to electrum there was a balance there, its all very odd. It looks like UB Electrum just steals your coins.
