Software center crashes and lags

Hey everyone.

So I was trying to install a few things (Mainly LibreOffice),
at first I saw that the software center was laggy, I couldn't scroll the window well.
But after some time I could finally click the install button, minimize the window
and listen to music.

But when I wanted to reopen the window my whole computer froze and I couldn't
do anything but to manually restart my computer...
Software center has been laggy on every use, I'll try to install LibreOffice once again
but I'd like to find a solution for this.

So is this a known issue? I've had ubuntu for quite some time before, and I've never
experienced any trouble using the software center. :/ I'll also add that all the other
programs worked well and fast except for the software center.

Greetings, Pixell.

Edit: SoftCenter couldn't repair the broken packages, but it seems that it didn't mess with the installation of OpenOffice. The program(SC) still lags a lot. (even though I didn't experience a crash this time.)
