No this is not a new installation. It worked for 1 day and went corrupt. Also there is no %APPDATA% in Windows 8. I also tried all command line prompts you suggested and I just got back an error saying it didn't recognize my input as a readable file or batch file. Please help. Can somebody recommend any online wallets that I can use for the meantime while I mine?

How do I run it with a different flag? Can you explain it a bit more in steps please? Sorry, I'm still new to this. Thanks!

Hello everybody! I am running windows 8 developer preview build and I came across an error saying "error loading Blkindex.dat." I have been checking other forums about this issue and they said trying to remove that file from their %APPDATA% but I'm pretty sure windows 8 did away with that and just has a tmp folder now instead. So I checked the tmp folder and it wasn't there either.

I'm 99.99% sure this isn't a windows 8 problem. I just need some help and any feedback will be greatly appreciated! Thanks!
