Primary Index ID no recognition

Hello,
I created a table (joodb_abra-afiliados) with primary index and another unique index with 3 fields.
The PRIMARY is an AUTO_INCREMENT int(1) type field exactly as joodb_sample table.
When creating new database, in step 2, JooDatabase is saying "The table has no primary index. Pleas define a ID field using PhpmyAdmin."
I understand it is not recognizing the existent primary index.
How could I solve that?
Environment:
Linux
Apache version 2.0.63
PHP version 5.2.8
MySQL 5.0.92 community log

can you please post the table structure in the following format.
CREATE TABLE IF NOT EXISTS 'jos_joodb_sample' (
'myid' int(1) NOT NULL AUTO_INCREMENT,
'title' varchar(100) NOT NULL,
'value' varchar(10) DEFAULT NULL,
'usefull' enum('Yes','No','Unknonwn') NOT NULL DEFAULT 'Yes',
....
PRIMARY KEY ('myid'),
KEY 'title' ('title'),
KEY 'state' ('state')
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=14 ;

Hi, Dirk, thank you for answering.
I saw that joodatabase was working for any other table in Joomla. So my conclusion was that there were something wrong with that special table. I deleted the table and recriated it, and all is working as expected.
