First sorry for my bad english, it is not my first language.

So, I was using sigil 0.7.4 normally until I had the brilliant idea of installing the dictionary in my language (pt_br) but something went wrong and sigil kept crashing so I decided to uninstall, re-install and forget about the dictionary, but after I did it, sigil wont open.
I saw somewhere on the forum that you have to delete remaining "traces" so I downloaded a program (revouninstaller) to uninstall sigil. After that all the times I tried installing sigil it would get through all installation steps, create the folders and icon and all but it doesn't open any epub file. I tried installing sigil 0.7.3, tried to reboot, tried to open as administrator, nothing works.
The only option I have left is formatting my computer but it would be a pain to install everything again... And if I can get it working again I wont even try installing the dictionary again
I'm using windows 7 x86, the currently installed version of sigil is 0.7.4 and I don't know if it interferes with anything but I have calibre and adobe digital editions installed as well. all the other programs are working fine and like I said previously sigil doesn't crash, it simply don't open at all.
Have anyone faced this problem? does anyone know what else I could do?
(sorry if I broke any forum rule, I just registered)
