You need to -
a. Move your IB keyfile from your old version to your new version ( you did make a backup, right? )
b. Make sure in IB prefs SSL v2 and v3 are checked and Miami SSL is UNchecked (you are using Genesis from WB3.9) No Genesis settings need to be changed.
c. In IB prefs Security, Ciphers, UNcheck 3DES. This may be causing slowdown.
