Counterwallet generates a 12 word seed. You must remember this (ie write it down). It is not saved on any server or on your computer. If you lose the seed you lose your account.
Alternatively you can select a password + custom URL. But the same logic applies: you must remember  password + URL, otherwise you permanently lose access.

You may have typed one word wrongly. Therefore you generated another address when you logged back in.

FLDC can be stored on any Bitcoin address. To view your balance, use blockscan.com. To transfer your FLDC you need to import them to Counterwallet first, which is simple if you know the private key.
