Hello,

I have Bitshares-PTS client version v1.0.0.0. When I try to open, I get the message: "Error loading block database. Do you want to rebuild the block database now"

I click OK, but then it says "Assertion failed", and refers to db/version_set.cc, line 715. It will not allow me to load the client

What do I need to do?

I have a backup file (if I need to reinstall, I will need guidance on what to do with the backup file)

Thank you
