Those files are backups, the highest number is the most recent version, the lowest number is the oldest.
You can rename or copy them to Default.wksp until you find one that works.
I highly recommend to not use one Workspace for everything. Use one workspace for each connection profile. Or even one workspace for each "topic" you are working one.
