You can update Miranda to stable version, restore db from backup (rename /youprofilename/youprofilename.dat.bak -> /youprofilename/youprofilename.dat) and disable updates.
But 0.95.13 is the latest version with old database format support, so you will be forever stuck on it.
oooo why that !!
if i used stable version i won't be able to get any new updates !!
so why that !
you did the new update why you know it will be slow , so why you did it ?
usually updates done for better preference , so why doing it if it make slow ?
i have now modern new fast computer , but Miranda after new updates last days is slow on startup
please find a fix for that , or let's choice between old and new use profile *.dat file
