Two weeks ago had to bury my old PS3 Slim that I bought new back in 2010 and got a second hand PS3 Super Slim. 

I put in a brand new SSD for a fresh new start. Everything was ok until I tried to get in the PsStore.  It opens the interface and inmediatly the psnetwork kicks me out, the store closes and i'm back to the PS3 menú. No error code, only a mesaage (see the picture above).

The internet and even the PS support (playstation experts) told me that sadly thats  a common problem  with thousands of users  that did the same as me, and the problem is basically lack of support from Sony. Something about the last PS3 servers don't support old accounts on other PS3  consoles. Etc.

Had tons of games on my PS3 store wishlist, please Sony fix this.
