In your phpgiftreg directory, what SQL scripts do you have? I'm at 1.5.5, so I have these:
1.0.x-to-1.1.0.sql
1.1.x-to-1.2.0.sql
1.2.x-to-1.3.0.sql
1.3.x-to-1.4.0.sql
1.4.x-to-1.5.0.sql
1.5.x-to-1.5.5.sql
After you download 1.5.5, run the scripts in order. e.g. if the latest script you have is 1.2.x-to-1.3.0.sql, you'd replace your code (.php files) and then run 1.3.x-to-1.4.0.sql, 1.4.x-to-1.5.0.sql and 1.5.x-to-1.5.5.sql in that order.
Hope this helps,
Ryan
