Unable to install IVR on PIKA

Attempting to install IVR via module admin onto PIKA, all other modules install correctly, receive error message:FATAL ERROR ALTER TABLE ivr CHANGE COLUMN announcement announcement VARCHAR ( 255 ) [DB Error: unknown error]

how about providing a little detail on your environment please?

versions of * and FreePBX, build info…

You might ask Ethan at schmooze, as he compiled the images for me. FreePBX 2.5.1.0
Asterisk 1.4.14.
I am having some other issues with this build also , cannot set time groups, goes to blank web page after apply, and won’t save group. Most other modules such as day/night work fine.
