I can't read the texts

[Halkengar]

I've installed Diogenes and put the TLG as well, but if I try to search for any author, Plato for instance, I can select him on the list (Plato. Phil. 0059) but when it's supposed to show the list of works the page simply goes blank. I've tried to search for other authors but the same problem occurs. The only situation in wich something different happens is when I search for Aristotle, and in that case I can select the works and passages of a text but then the page goes blank again.
