Import customer problem

Hi to all,

I think that I need your help. I’ll try to explain my BIG (BUG!) problem…

I have imported a customer CVS file from an old database I had, but now every time I click on the customer profile in the admin side, the REGISTRATION DATE field it updates all the times. And uptades the hour/day/month/year of my last click!

I have noticed that the problem instead it doesn’t appear with the new accounts that customers are creating. Their date it remain still, the old ones instead move and always update.

Can somebody help me please on this?

Thanks in advance for your kind help
