Fresh page and something wrong with updat

[magucio]

Hello everyone. Yesterday i downloaded Presta from official page and installed on my website. Of course after installed i went to admin page and checked everything and found information about my presta version. I have 1.7.4.3 version so i thought maybe i have to download updates (to 1.7.4.4). So i did this, but first i downloaded "1-click upgrade" module. I switched my site to maintenance and tried download upgrade like i said before. Unfortunely something went wrong and i got message with error "Operation canceled. An error happend". I dont know why so i need your help. Can someone explain my why i got this message? Every point was green

Thanks everyone for trying help
