Your filters do not work because the msgFilterRules.dat file, which contains your filters, could not be read. A new msgFilterRules.dat file will be created and a backup of the old file, called rulesbackup.dat, will be created in the same directory.
Chan eil na criathragan agad ag obair a chionn 's nach gabh am faidhle msgFilterRules.dat (far a bheil na criathragan agad) a leughadh. Thèid faidhle msgFilterRules.dat ùr a chruthachadh agus cuideachd lethbhreac glèidhidh dhen t-seann-fhaidhle (air a bhios rulesbackup.dat) san dearbh-phasgan.
