Does it work if you ask for $_SESSION["credits_system"] etc ?

The reason I ask is from the code above, you're using globally scoped 
variables, which would require you to be using either an old version 
of PHP on your test server, or have to manually enabled register_globals.

Register globals is of course a major security risk in that it 
pollutes your variable namespace with whatever the user feels like 
sending to your server in $_GET, $_POST, $_COOKIE etc etc. So your 
code can be easily manipulated into undefined behaviours unless you 
declare and initialise every variable it uses.

I think you need to look at phpinfo() for that server. Check 
register_globals, it will be 'off'.
Turn it 'off' on your test server so it mirrors the live environment 
and see if your code still works (it probably won't).

The other check to make with the hosting company - I've only seen 
this once or twice on cheap hosting :
See if they're using multiple servers. The session handler by default 
uses files, which are local to an individual server.

If you visit the 'page' again, you may well be being server from 
another web server in a cluster. Of course that server knows nothing 
about the local session files on the server you initially got sent 
the page from, cause they're on another machines' filesystem, thus 
replicating your problem.

The answer in that case is to register your own session handler (such 
as a DB) which resides on a known server.

I don't understand what you mean by that, can you expand some more ?
It's not clear how the database uses 'foldername' - is it 
concatenated as part of a query ?

If as noted above your host clusters servers, then you're SOL and 
will have to manage a central file repository or call across servers 
with fopen() etc to get at the [distributed] data in the "$foldername" path.
