Dave error

Hi. I'm using Dave for xmc4500 in my uni.
I had a problem with my computer memory so i did disk formatting.
And then i re-downloaded DAVE but i couldn.t use dave until now.
I'm using window 8.1
I received this error.
- Also Device Description Libraries are not found for selected Device in DAVE Library store.

I can't allocate pins for apps, add new apps and make new project.

please help me. Thanks in advance.
