Cannot download blockcchain

[amad0r]

Hi all, I'm having issues with literally every wallet I download (aside from bitcoin)
I'm currently mining TRC on Coinotron but I have nowhere to put my confirmed rewards because every time the blockchain downloads (whether it be for LTC, PPC, TRC, etc.,) it fails to read the block and I can't figure it out.
I'm running Windows 8 if that makes a difference.
Thank you
