Then the recovery tool of the next version will definitly help you claim them back.
Remember to not reuse addresses. If you have spent iotas from address A, never use it to receive iotas again.
IOTA uses one-time signatures, meaning if you sign multiple times using the same address, it will leak your private key and a hacker could guess it and steal your iotas. I think the 2.5.1 version prevents you from reusing addresses.
