Need help with userid 62 (administrator)

I need some help ASAP..please I have posted this in joomla board with no replyes so far and I need this solved fast because I want to put my portal on...

Hi!

I have just migrated everything from phpbb3 including users...
After that wen I loged in my administrator panel it told me that there was no administrator setup, my user id in phpbb3 was 2 so I changed the joomla tables to make me a super admin (it worked now I am a super admin), but I have problems now, I have followed the "how to make a super admin" somewhere but It cant be done because wen I migrated my users the user Id 62 belongs to one of my users, now even after I changed everything to make my user id (2) to be a super admin, all the system messages (for example PMS plugins) say that the message comes from the id62 username in this case aligra is the userid 62..some extension use the same id to control the frontend so now I dont know what to do?

Can someone explain me how can I this work?

My mysql knowledge is limited.. I'm sure that I have to change my userid to 62..but the user allready exists..please step by step tell me what I must do in what tables, I want to learn this..
