When trying to recover your account, you will need to reset your password. If you see the following message, it means something is affecting the link being sent in the recovery email.
invalid_request: UUID parsing failed: invalid length: expected length 32 for simple format, found 8
This is what the error looks like.
It is likely that a browser plugin or email client is trying to sanitize or modify the link in some way and that only the first 8 characters of the code we sent are being copied into to your browser's address bar.
We have seen this happen with users of the webmail clients for nifty.com and mail.com which wrap long lines of text (including links) and break the URL linking.
You can try manually copying and pasting the full URL from the email rather than clicking on it, but sometimes the mail client will have already messed up the link.
You can try viewing the email in plain text (consult your mail client documentation) or try clicking the link from your mobile phone's mail client and resetting your password there.
