(PS3) Crash during loading screen + 10102

Hello all,

Earlier today, I had my PS3 crash after a teleport to another location during a loading screen. Since then i've been unable to log in with any of the characters i've created with the 10102 error appearing every time. More worrying is that checking my save data on the Saved Data Utility shows me that the character i've played for several hours is now a "Lv. 0 adventurer" but it remembers the Area and World correctly.

When in game, I see my character on the screen with all the data intact (appearance, location, level, class, etc.) but I'm scared that this crash might've corrupted it beyond repair.

Is this crash linked to why I can no longer log into the game world or is it unrelated? Perhaps more importantly: will this crash force me to restart from scratch or can I somehow recover?
