Virus ti problem

[chuckceller]

hello all virus users,
i have a virus ti desktop and in the last week i havent been able to get any sound from it, i have tried reinstalling different updates even the latest one, tried resetting it etc.. nothing.. when i turn the virus on the loading bar on the display gets stuck right at the start and eventually the virus loads up but no sound comes from any of the outputs,
what also happens is when i load a patch any patch and soon as i turn a knob a 'E' come up to the left of the patch name, now i have no idea wot this means, is it a error? or wot does it mean and why does it come up, if anyone could help i would reeeallyy appreciate it.. last resort i might have to take it to my local music shop and get it sent out for repair.. its drivin me crazy not bein able to get it working..
thanks heapls!
