I have tried this and still the same. Yesterday before I asked the question, I was trying the same on this file>> admin_pm/users_registration.php and today I have followed your instructions and made the changes on the file you mentioned.
I also changed the $countryparam_Regions = "US"; to $countryparam_Regions = "GB"; and tried this way too. Still no luck. On the list I am seeing United States and California selected.
admin_pm/users_registration.php and webassist/plugins/registration/full/registration.php page, change line 377;
These 2 files seems to be the same ones. Do you think there is something wrong with my installation? I have followed the instructions.
After intallation I have found the 'webassist' folder still being in 'install_pm' I had to reload to the root folder of PowerMessanger manually to make image upload function for the CK Editor.
Your help will be appriciated. Thanks
