I am designing a circuit that uses the LP2951 adjustable micro power voltage regulator chip. I have gone through the tutorial on how to add a component correctly for simulation. I have downloaded the SPICE file (model) from the TI website and loaded into the component I created. I cannot seem to run the simulation without 152 errors.

Hoping to find a solution to this problem.

HERE IS THE MODEL FILE FOR THE LP2951....what's wrong with it or incompatible with multisim?
http://www.ti.com/product/lp2951-n#toolssoftware >> on the right side of the page is the SPICE files for the LP2951
HELP...

Did you look at the file with a text editor? Here are the first 4 lines:
**$ENCRYPTED_LIB
**$INTERFACE
*$
* LP2951 Model
Unless you have the means of decrypting the file, I doubt this model will do you much good. The only things in plain text are some comments and the .SUBCKT declaration and .ENDS lines.
