Update program deleted all my existing maps and replaced them with a map of South East Asia. Why?

Appalling software program. Update deleted everything. I try MyDrive, enter password, continual error message "We are having trouble Accessing TomTom services. Please try again later".24 hours later? Same rubbish. Updates & News insists my Tom Tom 520 is up to date...!
