two forums problems

I did a lot of searching, but I can't seem to get two forums to run on the same site.  It has the same domain such as www.webwiz.net/example1/forum and the other forum I wanted on something like www.webwiz.net/example1/forum and I placed both forums in another private folder that's not being shared.  When I access the new one I still see the banner on top of the old one.
I read to go into the  common.asp set
change Dim blnUseApplicationVariables = false

but when I do that nothing works.  I changed the cookies settings on one of them.  On the first forum I logged in as administroator and turned off active users.  The second forum I login as administrator with the default "letmein", it logs me in alright, but then when I click on admin button so I can disable active users I get this "Sorry, only members with sufficient permission can access this page."

I'm sorry as I know this has probably been posted a lot of times, but I can't seem to get it. 
Thanks

I went into both common.asp files in both forums and changed the cookies to something total different.  Basically say one for is example1 all cookies in both common.asp I changed to exp1 and for the other forum both common.asp files I changed to exp2 and when I logged in the new forum, which I'll call example 2 with administrator "letmein" I still cannot get into the administrator panel.

I then went into each common.asp file and tried changing
Dim blnUseApplicationVariables    'Set to true if application varibles are used to
Dim blnUseApplicationVariables    = false

and on either forum I do this I get this error in the browser

Microsoft VBScript compilation error '800a0401'

Expected end of statement

/example2/forum/common.asp, line 122

Dim blnUseApplicationVariables    = false


Let me ask you, when you say subdomain do you  mean for example if I owned say http://www.webwiz.net and I wanted a non-profit site called example1 and another non-profit site for another charity called example2 and the links were http://www.webwiz.net/example1 and http://www.webwiz.net/example2 is this what you consider subdomain?  Because this is the way it's setup currently.

Thank you so much for the reply.  I should have done another search I just opened up my text editor and did a search and changed the first thing I saw.  Now I changed correct value.  I didn't relieze I was changing the decleration and I thought it was being declared in another file for some strnage reason.  Anyway now everything looks like a separete forum

I'm still not able to login to the admin folder.  I tried with my browser pointing to just the admin folder and either files frame_set.asp and even the forum_configure.asp and it keeps saying

Sorry, only members with sufficient permission can access this page.  I'm not sure why I'm having this problem.  I tried recreating the database and it's still saying I don't have premission

I'm not able to change anything now though.  I keep getting this error

Microsoft JET Database Engine error '80040e09'
Cannot update. Database or object is read-only.
/forum/admin/forum_configure.asp, line 144

I checked the mdb file and it's not read only and it's in the same folder as the othe database, so I know access to it is ok
