offline sorter 2.8 could not import new McRack data

Hello. I updated McRack to 4.3.0 version. The new data files could not be imported into offline sorter v2.8.8. The error message showed: "can't open mcs data files". Actually, the extension of the data is .mcd.
Has the data format has be changed in the new McRack version? if so, is there anyway to convert the data file back to old version? Thank you.

The data format may change from version to version, if there are new parameters to store in the data.

The reading of data is always compatible to old versions. Offline Sorter probably uses our OCX component, so you should also install the new MC_Rack version on the machine on which you are using Offline Sorter. Then the latest OCX is also installed on this machine.
