Access laptop

[hardy49]

My husband has just got a new laptop with Vista installed on it.
This morning we had somebody come to set up the e-mail for us.He asked if we needed the password but seeing as my husband will be the only one using it we said we did not and he said he would delete that facility.We have turned it on an off since he left and it was ok.However,my husband has just installed some software for his camera and the box asking for his password appeared.When he put his password in a message saying "user profile service failed the log-on - user profile cannot be loaded"
Every time we insert the password we get this message and so we cannot open the Windows.Any help please ?
