Firewall rule problems

We have a Sonicwall NSA 2400...  We were making some tweaks to our Firewall rules and accidentally deleted a WAN->LAN rule and now some of our websites won't connect.  For example my Dropbox service won't connect, https won't connect, and the internet has slowed down a bit.  

Within the logs it looks like it's now dropping connection to Dropbox servers and listing it as Intrusion Prevention.  ALso, we use a website for our Accounting and now that site will not connect over and https connection.  Any ideas on how to get this rule set back up without letting the world in?

Well, the deletion was made within the GUI to CLI so I'm assuming it was written to.

We tracked down a problem.  There were 3 rules related to http,https, & ICMP that were deleted.
 
The rule structure were as follows:

1. DMZ->LAN --- allow:  http, https, ICMP
2.WAN->LAN --- allow:  http, https, ICMP
3.WAN->DMZ --- allow:  http, https, ICMP
