Top arc links dropped

After translating the links in the top arc the links dropped a few pixels..

Where/how do i put em back to where they belong? Even translating em back to english does not help.

(Site is not reachable yet from the outside, so no sitelink)

Added margins as a temp fex, but doesnt explain what happened :S

.top_arc_left {
margin-top:-9px;
width:49.5%;
float:left;
text-align:right;
}

.top_arc_right {
margin-top:-9px;
width:49.5%;
float:right;
}

Ok, that fix is ok. Give us link when you put your site online if you want from us to have a look. It seams to me from picture that font-size of items in above menu pushed them down.
