The report -no observations- could arise because of a problem with the
data you feed to -levpet-, e.g. as a consequence of missing values or
numeric data in string variables. What you are seeing does not
_necessarily_ indicate a problem with -levpet-. 

In any case, you can use Stata to answer your own question. -search
levpet- indicates only one version of -levpet-, the one you have
downloaded.

There is a error in the levpet module I installed from that link. One of
the subprograms I had to download was that one, the nllp_bs_gmm. But I
don't know what could it be. 
When I run this...

   levpet lUSY, free(lUSL) proxy (lUSM) capital(lUSK) revenue
no observations
error #2000 occurred in program nllp_bs_gmm
r(196);


[P]     error . . . . . . . . . . . . . . . . . . . . . . . .  Return
code 196
        nl___________ refused query, rc= ___________;
        error # _________ occurred in program nl_________;
        Your nlfunc program did not work properly with the nl command.

(end of search) 

Is there one possibility of finding another version??

If you do so you will find a link to SJ-4-2, click on st0060.
Than within the window that opens next look half way down on the right.
There you will see (click here to install). The rest is
self-explanatory.
