Hi, i've been running FB 1.5 RC4 for several months and i've had no
problems.
Now i want to change to 1.5 final so after reading the installation
notes in the Release Notes pdf i backup my DB, uninstall my existing
version and install 1.5 final.

I can connect fine to the restored database thru IBExpert and my
application and edit records but when i try to save a new record i'm
getting a "Connection was lost to database:" error from IBExpert and
from both i get "Unsuccessful execution caused by a system error that
precludes successful execution of subsequent statements. Unable to
complete network request to host 'localhost'. Error reading data from
the connection. An existing connection was forcibly closed by the
remote host."

I also had this problem with RC8 which is why i waited for the final.

What am i missing/doing wrong ?
