st: xtserial and xtcsd do not run

[itchiftc@rumms.uni-mannheim.de]

Dear all,

I'm doing some analysis with panel data. For this reason, today I  
installed via ssc the functions xtserial, xtcsd, xttest0-3 and  
pantest2. Interestingly, the xtserial and xtcsd functions do not run.  
The xttest and the pantest2 functions, however, work without any  
problems. With xtserial I tried for example the following (after  
declaring the data to be time series using "tsset bankid counter"):
-xtserial ln_medbas relfva relloans

But I received the following error message:
   _TS_p_delta_getnumb():  3499  strtoreal() not found
 _TS_p_delta_increment():     -  function returned error
           _TS_p_delta():     -  function returned error
                 <istmt>:     -  function returned error
The same came when I tried xtcsd.

I tried to install xtserial again, but Stata said it is already  
installed. Then I tried to uninstall it, but it said it cannot find  
the package...

Does anybody know what may be the problem or am I doing something wrong?

Thanks a lot in advance!
Ida
