Looking for someone to flash U1MB

Hi Folks,  I attempted the .ATR upgrade of U1MB  to version 2,  and it failed on the first bank.  When it asked me if I wanted to restart,  I hit 'n'  assuming that would take me back to SpartaDOSX to re-load the program.   Of course not

Is there someone here who would (for a fee) flash my U1MB for me?   

Thanks much,
