Run-time error 2147220990

Hi,

When trying to update pay period to the next pay period I get an error of run-time error'-2147220990 (80040202)'

Cannot open output file (bad file name, in us by other application). 

Please assist as I am 3 months behind with pay slips due to registration issue i had with pastel payroll and HR and need to finalise them as soon as possible
