Sync/Memory problem

[antjones21]

I'm unable to sync my Sprint Diamond with my PC. when I open up Windows Mobile Device Center I get a red "X" with the word Error displayed next to it. Also Whenever I try to unzip or install a program on the phone itself, the installaton process fails. I can't even open up an attachment in my email. The first time I noticed was last week and I did a hard reset and it went away. Now it's doing it again. Along with the issues mentioned, when I go to the remove programs featur in the settings menu, no programs show up at all and I have programs installed. I falsh the rom to the new rom that is offered from the HTC website for the CDMA sprint Diamond.

Has anyone ever had this problems before? Or know what my be causing this.

thanks
