Anyone know what this error means??

having problems with docs to go (Documentstogo (in the bin) lol. Invalid COD?)

So deleted docs to go from the phone, to try installing the new version without the old one on there, on rebooting the phone at first it was okay, then i connected to desktop manager and was messing around with mundu, it tried to put docs back on so i unticked the button, anyway on reboot i got a nasty screen within about 5 seconds

looks like an application window with a big cross through it, and error code below it of 549..

thinking i'd bricked it i tried last resort of connecting back to DM it didnt pickup the phone or any pin, but i clicked on add applications anyway, and thankfully it found the phone, put docstogo back on and the phone works fine :-S take it off and same error, surely you dont need docs to go installed so whats going on??

Also I can't find my applications on the pc?? i've checked the data folder, i've done a search for "mundu" as thats one program i know i have, and they are no where to be found, hidden and system files are set to show.. but where are they????? i have a new mundu that wont install so again i want to delete it off the phone /pc and start from scratch..

Something sounds seriously wrong with my phone :( its a new one i just got in exhance for my old one.. grrrr..

Probably a corrupt file somewhere. Reload the OS and don't mess with it!

Well i've kinda sorted it ish.

i removed the software again and did the upgrade with only one reboot and i didnt get the nasty screen as that only happens on subsiquent reboots, however now desktop manager (4.7) is convinced i have documents to go installed twice, it is hapily leaving one alone but wants to do the infamous downgrade on the other copy grrr.. i am now going to uninstall DM and reinstall it and see what it thinks of my phone then. lol.
what a joke.
