Dream weaver 8 synchronization window

hello there
I do not know why but from now on dreamweaver 8 does not show its entries filled with filenames as it should and instead it leaves them in blank so I do not know what files I have to upload. The synchronization might still work but the synchronized entries appear in blank so I cannot really control what kind of synchronization is carried out and it is pissing me off because this synchronization tool from dreamweaver is really useful and not being able to use it is like a pain in the ass.
Any suggestion?
