Hi, very odd. The update/installer simply replaces all working parts (EXE, DLL, etc) and does nothing for (or 'to') any INI files (etc - the parts of your profiles)
Do you have the program set to make automatic profile backups? (Preferences menu > Options > Expert tab > centre option/s). If so, you can presumably find the most-recent backup copy of a given profile (stored in compressed .SPS files) in the path shown. You can usually simply double-click SPS files to Import them (or, Profiles menu > Import profile > browse to & select the SPS file/s)
Otherwise, you probably need to re-create them manually.
