Basic Payroll Tool and submission to HMRC

Our company has had to download the Basic Payroll to a new computer. We have no access to the previous bookkeeper's computer and only have the December payslips to work from. I downloaded the Basic Payroll, added our employees and all their details. I then did the January payroll and submitted it to HMRC. The FPS and EPS said "successful". I can see on HMRC PAYE the previous months' details and payments so I know I am using the right HMRC account. However the January month has not appeared on our account. I thought it might be because I was late with Jan PAYE submission, but I did get a late notice message when I submitted from HMRC via our account so it has been received onto our account. I then submitted, timeously, the Feb FPS and EPS. Again said "successful". However, the details are not on our HMRC PAYE account. The monthly payments which match what the Basic Payroll said we owed are showing as "unallocated payments". Please can someone advise me as to what I am doing wrong?
