If you're on Windows you may use 7zip to extract the blk0001.dat file to %APPDATA%\SummerCoinV2\
I think the blockchain files are not compatible accross different OSes
You'd better get a blockchain from a linux machine to another linux machine and ditto for windows.
32 and 64bit windows blockchains are interchangeable however. Or at least that worked for me
You will get help soon, I will alert a technical member here.
ENJOY THE CHRISTMAS SEASON!
