During launch of the application I get the following error:
Unable to load address book file abook.mab. It may be read-only, or locked by another application. Please try again later.
If I skip it, I cannot add a new contact in the address book. Has anyone got an answer to this please.

You can try following steps:
make a copy of abook.mab.bak and call it, for example, myaddbook.mab, then save it wherever you want
install this extension --> http://nic-nac-project.org/~kaosmos/morecols-en.html
once installed, open addressbook, go in Tools --> Actions for addressbook --> Import mab and import myaddbook.mab
now you should have a new addressbook, but probably you don't see nothing inside
select it right-clicking and choose "Restore/Recover"
you'll have another new addressbook that could have your addresses
Please check also permission for that folder/subfolder should read/write access.
