Batch file loop issue - ends batch file - loops

Question

I have problem with my batch file.
#echo off
:START
echo Are you ready?
SET logpath=xxx
:COPY
pause
xxx
:FIRST
for /f %%g IN (hostnames.txt) do (
::xcopy "xxx*.*" \\%%g\c$\temp\ /f /s /y /i
echo PC %%g >> %logpath%\xxx
echo %%g > appname.txt
psexec -h \\%%g cmd /c msiexec /i xxx
IF '%ERRORLEVEL%'=='0' (
echo xxx Success! >> %logpath%\xxx.txt
) else (
echo xxx Error is %ERRORLEVEL%. >> %logpath%\xxx.txt
)
psexec -h \\%%g cmd /c msiexec /i xxx
IF '%ERRORLEVEL%'=='0' (
echo xxx Success! >> %logpath%\xxx.txt
) else (
echo xxx Error is %ERRORLEVEL%. >> %logpath%\xxx.txt
)
:SECOND
psexec -h \\%%g cmd /c MsiExec.exe /I{xxx} /passive /norestart
IF '%ERRORLEVEL%'=='0' (
echo test {...-xxx} uninstalled! >> %logpath%\xxx.txt
goto THIRD
)
psexec -h \\%%g cmd /c msiexec /x "{xxx}" /passive /norestart
IF '%ERRORLEVEL%'=='0' (
echo Pierwszy {...-xxx} uninstalled! >> %logpath%\xxx.txt
goto THIRD
)
::Like 15 times uninstalling different apps
:THIRD
for /f %%g in (appname.txt) do taskkill -s %%g -im xxx.exe -f
for /f %%g in (appname.txt) do psexec -h \\%%g cmd /c msiexec /i xxx /passive /norestart
IF '%ERRORLEVEL%'=='0' (
echo xxx Success! >> %logpath%\xxx.txt
) else (
echo xxx. Error is %ERRORLEVEL%. >> %logpath%\xxx.txt
)
for /f %%g in (appname.txt) do psexec -h \\%%g cmd /c regedit /s xxx.reg
for /f %%g in (appname.txt) do psexec -h \\%%g cmd /c del c:\temp\xxx\*.* /f /s /q
echo. >> %logpath%\xxx.txt
echo. >> %logpath%\xxx.txt
)
At first, like You can see in the THIRD section I need to use for /f %%g in (appname.txt) do psexec -h instead of psexec -h, because psexec fails and it's "losing" hostname and this is the only workaround which I have found by myself.
Second thing (most important) is that when batch runs to the end (to the last ")") it stops. Like the first loop for was ended and it doesn't get new hostname from file hostnames.txt
I would be gratefull for any ideas how to make it work
