Hi I'm new to Bitcoins. After downloading Bitcoin 0.3.22 for Windows yesterday, I had no issues with opening it. However, now when trying to open it, I get the following error in Dutch (I'm Dutch): 'Fout bij laden van bestand blkindex.dat'. The literal translation is 'Error with loading of file blkindex.dat'. How do I fix this?

Thanks in advance,

Zyphix
