Version 0.5.0.1-Beta I forgot about my bitcoin account until recently.  I have the software version listed above and my last real transaction was in 2012.  I don't remember my password, but my 12 year old PC does.  Do I need to transfer this to a wallet?  I have done a test transfer with $100 or so but it hasn't kicked off.  I noticed the S/W is "Catching up" and "Downloaded 173968 blocks of transaction history".  And "Last received block was generated 2121 days ago".  Any advice?  Do I need to wait for it to "Catch up"?  Thanks.
Congratulations! Safely exit the software, create a safe backup copy (check that everything is copied correctly) and upgrade to the newest official version for your operating system. You will need approximately 150GB of storage in total for the full blockchain once it finishes catching up, including what you have already, or you can set -prune= mode.
