Overlay not working

Eyy fellows, I've been having a problem with RTST: My overlay doesn't work.
I have Windows 8.1, 64 bit.
I had this problem about a couple of months ago but at the time I left ps2, so I didn't mind.
Since 2 weeks I started to play again, in the first week it worked just fine but than I started having this problem (once again).
Every time I start the recursion I get this:
"Starting search... size:2232320
Adress Match 7ffdad3ca552
Read: fffedc1f
vTable not found.
Failed compatibility test. RTST should be started prior to launching PS2.
Console display for RTST PS2 DLL injector.
To turn this display off go under
Tools-Options-Configure and uncheck Launcher Window

rtst_d3doverlay_x64.ddl loaded.
Install Hooks Function found.
Attempting hook-- try count: 3.
Hook ready"

My overlay doesn't work, no achievements, no crosshair but I still can hear the voice lines.
This what I've done:
• Tried different display options
• Redowloaded RTST about 2 times
• Started as admin
even after this, nothing happened.
I would really appreciate some help on how to fix it.
Don't worry, take your time :)

Do you have other overlay software running? Steam, ts3, overwolf, raptr, riva statistics?

multiple overlays conflict with each other.

I tried without any other overlay software, still not working :/

Fixed, this is what I did:

- In-Game Overlay set at x64 and at Impact
- Started RTST after PS2
- Program Files x86 > Recursion > Recursion Tracker > rtst_run_dx64 (right click, run as admin)

Maybe the last step might be useless, but I only listed the things I did before I fixed it :)
