Invalid login after apex upgrade

Question

I upgraded apex for Oracle XE to apex 3.2.1. Ran all the scripts and everything seemed fine. Ran the script to change the admin password that worked as well.
However when I go to either of the login pages(one that has the workspace and the one that has just username and password) from internet explorer
I keep getting invalid login credintials
I tried the below solution from the this thread How Gain Access When Locked Out of Developer Workspace
I keep getting 0 rows updated after running this
update apex_030200.wwv_flow_fnd_user set change_password_on_first_use ='N'+
where lower(user_name) = 'admin';
I even tried the update without the where clause and still got 0 rows updated.
here's a quote from the thread
Hi All,
The lockout message I received was:
Access denied by Application security check
Application access restricted to internal workspace users.
Return to application.
I logged in as SYSDBA and ran the following scripts:
First change the password for the Internal ADMIN account (the one i was locked out of)
SQL> @apxxepwd <new password>
then
SQL> update apex_030200.wwv_flow_fnd_user set change_password_on_first_use ='N'
where lower(user_name) = 'admin';
+1 row updated+
SQL> commit;
--Note: schema name apex_030200 will depend on version of APEX you are using and your installation. I am using version 3.2.0.00.27+
Finally log into APEX using the two-field security form with the admin account. Make any changes to the workspace or user accounts. Note that after repeated attempts to login, some accounts may be locked, as was the case with me.
Hope this helps somebody else.
Regards,
Glenroy

Ok I got the admin user to work. However when I try to import an app I get this
"ORA-02291: integrity constraint (FLOWS_FILES.WWV_FLOW_FILE_OBJ_FK) violated - parent key not found"
Error uploading export file."
I get this is i use an app from apex 2.1 or even when I tried to import the sample app I exported from 3.2.
I wonder if there is some type of permissions issue with the admin account since I created it manually I was not sure what to put in the fields...
