Hi,
I am trying to run the LM25011 PSpice Transient Model from the product page (https://www.ti.com/product/LM25011#design-development) with PSpice for TI (PSpice_TI 17.4-2020 S006 Windows SPB 64-bit Edition) on Windows 10 Pro. The simulation fails and does not produce any usable output at all. I am very new to PSpice so it could be just me using the software wrong. What I tried so far:
When opening the project a message pops up:
"INFO(ORCAP-2459): TI model librariers have been updated to the lates version in this design. Refer to the session logs for details of these updates."
And then a message that it is a read-only file:
"WARNING(ORCAP-1682): File is read only or in use. Changes will not be saved back to the original file named <path to my folder>\snvm168\LM25011_TRAN.opj"
I can the open for example the "STARTUP_TRAN" schematic and no simulation profile is selected. By selecting the "STARTUP_TRAN-STARTUP" simulation profile the PSpice asks me to save the project under a new name which I tried but at the end of the process it says that the read-only file can not be saved. The schematic closes and I can open it again this time with the selected simulation profile.
After pressing the play button it simulates forever (there is also no percentage of how much it has finished visible) and I manually stopped the simulation at TIME=0.14 which opens up the PSpice Runtime Settings:
Output of the simulation:

**** Interrupt ****
I press "OK& Resume Simulation" and a couple of messages pop up.
First message:
"There are no data values in section number 1 Ignoring this section"
Second message:
"There are no data values in section number 2 Ignoring this section"
Third message:
"Analysis failed on <path to my folder>\snvm168\lm25011_tran-PSpiceFiles\STARTUP_TRAN\STARTUP_TRAN\STARTUP_TRAN.dat"
The same behavior also occurs with the other schematics: LINE_TRAN, LOAD_TRAN, STEADYSTATE_TRAN.
What am I doing wrong or is there something wrong with the project?
Edit: Sorry for the long post, I tried to put the simulation output in a Code environment but it keeps telling me, that I am not allowed to do so.
