UCC24624: SIMPLIS Model problem

Part Number: UCC24624

Hello E2E.

I would like to simulate UCC24624 based on UCC24624 SIMPLIS Model downloaded from www.ti.com/.../toolssoftware. I actually use Release 8.10h of SIMetrixSIMplis elements (free version) software.

When I wanted to start simulation under SIMplis my PC shows message in "Command Shell":
*** Warning ***: Another instance of Elements appears to be running. Schematic auto-save will be disabled for this instance
*** ERROR *** (open_loop_LLC_SR_.net;138): Decryption failed: Unable to decrypt the data.

Could you help me with it? I was not able to solve this problem. How could I start simulation and get some simulation results of this circuit?

    I just did download and ran. It is running and not showing what you mentioned warning and error. Can you re-boot your computer and open Simplis and from Simplis open "open_loop_LLC_SR_.sxsch"? Make sure you open this file within that folder and with all sub-folders in that folder.

    Thanks for your reply.
    I tried to follow your recommendations. I performed 2 attempts on 2 different PC but situation was not changed.
    Did you use free demo version of SIMetrix/SIMplis SW or full version?
    I contacted SIMetrix/SIMplis support. I received information that this particular simulation, as it is available on www.ti.com/.../toolssoftware, required full version of SIMetrix/SIMplis SW.

    It is required to use full version for this model.
