That feature is hit and miss to be perfectly blunt. It should be only used as a last resort. Did you happen to back up your save before you did the swap?
Thats because this version of FMRTE was developed to work with the older version of FM.
Typically, the day after they launch the first version of FMRTE, Football Manager updates.
As is shown in the original post, you should run Steam in Offline Mode so it doesn't automatically update your FM
seriously stop guys always ask when will release the new version! we are all anxious to see him leave but it is useless to seek constantly ... it will be released when it's ready ... maybe this weekend ... maybe later ... please let BRACA and his team work peacefully
