Diamond lost MMS. WAP and X-cricket MDN button in registry.

[mazimi777]

PLease help!! This whole thing started when I got my phone it came flashed to cricket with Juicy3 ROM mms WAP worked fine. Then I lost MMS but internet worked fine, while trying to fix it I installed a app HD Manila 1.01 from www.down4V.com it came in RAR form the app would not instal and gave me an error. Next thing I know all my internet settings were erased. So I tried to put the setttings back in according to cellaholics instructions on Howards Forum, I noticed the X-cricket-MDN button was gone located in KLM\Software\ArcSoft\ArcSoft MMS UA\config\mm1\WspHeader so I tried to put it in by pushing new now I can't delete it and am worried I have really screwed up. If anyone knows how I lost this button or how I can get my internet and MMS back please help!!!
