Not to long ago a major Internet security risk was made public know as "Heartbleed".
Rather than have me explain it to you this video can do that: https://vimeo.com/91425662
Even if you don't think GalCiv was directly affected you should at least change your password if you use the same or similar login info on other sites as Heartbleed affected about 2/3 of the entire internet and your information could have been picked up anywhere! Don't let your investment in GalCiv be ruined because of this.
This can potentially also mean personal information like SSN#, Credit Card #, address, etc. could have also been compromised keep an eye out for problems with those too.
