System

Linux OS (hosted)
sugarcrm 4.5
MySQL version 4.1.21-standard-log
PHP version 5.1.6
Kernel version 2.6.17.13 Linux

after upgrading to 4.5 module loader stopped working. it sends me to a screen with a sugar license. It also gives me two options. One to install from sugarexchange, one to install from hard drive. When I select anything install from hard drive it dosent't go anywhere.
It also says your credentials are not registered but I cant register it.

Mass delte does now work either. In email when I select all an then on the mass update menu click delete, it says "are you sure you want to delete the records?" When I say yes it says "you muct select at least one record to proceed"

Can anyone help me out please.


Thanks
