Uploading MIBS

Uploading MIBS

Hi,

I uploaded the specific MIBS for the device and when i select the MIB i get an error "
Error parsing MIB:AIRSPAN-ASMAX-BS-COMMON-MIB_Draft14.mib
Exception while loading MIB:IMPORTS failed: Could not open file C:/PROGRA~1/ADVENT~1/ME/OPMANA~1/./mibs/INET-ADDRESS-MIB "

I tried to upload the MIBS again but still the same, i am using free edition of OpManager . Is there way to delete the MIBS and how do i overcome this error.
