Can I convert my bitcoin core wallet so I may use it in electrum or is electrum able to import and use my bitcoin core wallet as its own.  I'm tired of the huge block file.

Thanks

I am helping a friend with their new crytocurrency(non scrypt).   I set bfgminer up and it finds the pool and begins to mine, but all the blocks it finds are rejected. 

Here is my current cmd.
bfgminer.exe -o 127.0.0.1:9336 -u madhatr -p ** --coinbase-addr 1P4Yhqt2eXLYY3QerujY1gT58cnXt2smSi --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S all --no-longpoll --no-submit-stale --no-stratum --disable-rejecting

Now keep in mind the last 4 (--no-longpoll --no-submit-stale --no-stratum --disable-rejecting) have been tested with them in there or not in there while trying to figure out what is wrong.  I also tried the --no-gbt and --no-getwork

My usb is a sapphire @333Mh/s  the difficulty is next to nothing. When I mine using the qt program on CPU it seems to work fine.

Any ideas?
