ks.test troubles

Hi there!

I have two little different data.  One is a computer test on people, the
other is a paper and pencil test.  two boxplots show me that the data is
almost the same.

So now I'd like to know if I could handle all data as one, by testing
with ks.test:

====

ks.test(el$angststoer, fl$angststoer)

Two-sample Kolmogorov-Smirnov test

data:  el$angststoer and fl$angststoer 
D = 0.1413, p-value = 0.9112
alternative hypothesis: two-sided 

Warning message:
In ks.test(el$angststoer, fl$angststoer) :
  cannot compute correct p-values with ties
====

Ok, so how can I get the p-value?

I tried two tests:
====

ks.test(fl$angststoer, "dnorm")

One-sample Kolmogorov-Smirnov test

data:  fl$angststoer 
D = 0.8109, p-value < 2.2e-16
alternative hypothesis: two-sided 

Warning message:
In ks.test(fl$angststoer, "dnorm") :
  cannot compute correct p-values with ties
====

so I see that this message in the first one, depends on fl$angststoer.

The I have on this two vectors:

Doesn't seem to be a problem?

What can I do for a good computation?

Thanks,
