How to upgrade to 65.0 files:
Assuming your system is 64 bit.
Can you:
1. Download http://portal.vodia.com/downloads/pbx/win64/pbxctrl-v65.0-64.exe , rename it to pbxctrl.exe (if it's 32 bit, replace 64 with 32 in this link)
2. Download http://portal.vodia.com/downloads/pbx/dat/pbxctrl-65.0.dat, rename it to pbxctrl.dat
3. Install the msvcr120.dll and opus.dll downloadable from here: https://doc.vodia.com/install_win
Replace the existing files (.exe and .dat in your current working directory on your server) with both of these files, and restart the service?
