Link Point error

[ctcentralinfo]

I uninstalled linkpoint to try to reinstall the data and I am getting this error message:

1054 Unknown column 'avs_response' in 'zen_linkpoint_api'
in:
[ALTER TABLE zen_linkpoint_api ADD r_error varchar(250) NOT NULL default '' after avs_response]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

I tried this patch:

ALTER TABLE orders change lp_avs lp_avs VARCHAR( 25 ) NOT NULL DEFAULT '';
ALTER TABLE orders change lp_trans_num lp_trans_num int(11) NOT NULL DEFAULT 0;

I got this error message:

Error Failed: 2
Error ERROR: Cannot CHANGE column lp_avs because it does not exist.
Error ERROR: Cannot CHANGE column lp_trans_num because it does not exist.
