new version 5.0 not working

i uninstalled my last version and installed the new 5.0 version of the stuido
i replaced the old runtime arx files in my projects with the new ones and it will not work
when i load the run time it says runtime 4.2.1.0 loaded
when i load the project it fails
in the studio when i double click on the form to bring up the intelligent help and select
load_project,project_export,project_getforms,project_load,project_saveas,project_unload
i get that error to report to microsoft then the program closes
all other items are ok when selected even project_import.

this might be in the right place so i'm going to post to another place just in case

also when i installed 5.0 i saved a project and now that i have uninstalled 5.0 and reinstalled my old one it will not open the project
please is there a way to retrieve it. it's alot of work to redo

i'm really really upset but still love the program
thanks

There's no need to post in multiple places, we'll see it...
I'm going to lock this topic & continue the conversions, here in the correct location.
