My circuit will run on other computers but won't run on mine

for some reason when i run the psim file the data gets truncated and there is no waveform in the simview, but when i run it on my pc it works. I tried making different circuits and they work fine except for this one, so I am not sure what is the problem here. These are the spefication of my circuit:

SIX-PULSE FULLY-CONTROLLED
THREE-PHASE BRIDGE RECTIFIER

i. 3-phase sinusoidal voltage source with 45 VRMS/phase and 50 Hz frequency.
ii. 3-phase thyristor bridge.
iii. Voltage sensor (to sense VR and VB).
iv. Comparator (to compare voltage between VR and VB with 0 V).
v. Alpha controller with 50 Hz frequency and 120° wide pulse duration.
vi. 2 x DC voltage source (1 V to activate the alpha controller and the other to represent the firing angle in degree).
vii. 4 x voltage probe to measure all three phase voltages as well as the pulse to the thyristor.
viii. 1 x voltage probe (node-to-node) to measure the output voltage.
ix. 3 x current probe to measure all three phase/line currents

P.S i'm an undergraduate degree student with no money

    Without your PSIM schematic, it is not possible to know the reason for your problem.

    Here are a few guesses:

     - The Settings in the Option menu restricted the data size for the simulation result.

     - If you have copied this PSIM file from another computer, its subcircuit files and parameter files was not copied. Please use "Save In Package File" to collect all the related files into one package and copy it over.

     - The PSIM on different computers are of different versions. The functionalities in a newer version is not available in the older version.

     - You made modifications which cause convergence failures.

     

    There may be other reasons.
