if you mean the coins in your old wallet? These are safe: the blockchain continued, but with a different wallet. as soon as you have the new wallet, replace the old installation with new installation, and you will have both your new and old coins!
I hope the devs will give a good noob friendly instructions for this!
if I'm around I'm willing to assist as well..
You can withdraw from my pool without problem. but no need a wallet to see them. this will by fixed by the devs, with release of new windows wallet.
Mining-man is closing the pool (see earlier topics) and this might be a problem if you still have coins there.
Contact me otherwise right now on the pool irc: freenode #war-mining and I will help you on how to coins out of my pool..
