my wallet wont work aswell.tried just about everything.error says "cant initialize keypool"
if i remove my wallet.dat and use fresh one it works but that means i will lose about 7k coins

It looks like you are using the right wallet version; I would guess that there might be some type of issue with the wallet file. I would check the block explorer to make sure of the amount of coins at each address and then if it shows correctly use the dumpprivkey and importprivkey commands in the debug console to restore the coins in a new wallet. (If you can get the dumprivkey command to run on the wallet that won't load.) If not, you could try to use an old backup that loads fine and that might be good enough to run dumpprivkey to get the private key information out so you can restore your coins.
Best of luck!
How do i do that when wallet wont even open?
Thanks for posting Lightsplasher, your solution should fix most "Common" problems,
And for HunterS i'm not sure what would save your coins, people need to be more careful with their wallets, especially don't make any changes while CwC wallet is running.
Do you have the Address of the 7k coins? i don't know if there is much i can do, if you post your wallet address you might get some kind donations from the community although don't expect too much.
And as mentioned in the thread several times before.
