Install eM Client on new PC, its so slow now?

I reinstalled windows and eM Client and now eM Client seems so much slower. Any ideas?

Loading messages can take for ever or never at all (swirly bar for 30 minutes). Are there any preleminary settings I should input so this client has proper settings? 

On my old install everything was nice and fast.

Is there a way to import settings form my old client? I still have the old Windows install on my second harddrive if I can somehow copy over settings. I also have many quicktexts id like to transfer over if possible.

Is there anyway
