got any pc gurus here,,,i have been having some major dramas with my pc ,im running xt telecom stick and 2 saturdays ago my net stopped would connect but not view web pages ,after many hassles was told by telecom that in my area others were having same trouble ,9 days went by still no net so bought a vodafone prepay stick which got me up and running ,,,yesterday the missus down loaded at work the last software from telecom on a flashdrive bought it home download on this pc ,reinstalled xt software a great back up and running ,,now when i shut off the pc and restart i get msgs of invalid enter and cant connect to net only way i can i unistall software and reinstall ,this problem was here before the missus downloaded the flashdrive ,how can i fix this ,i use avg which seems ok does the trick ,cheers jason

cheers SS but im in nelson ,so what you use i go for the free stuff

Is invalid enter the entire error message?

I doubt it is virus related so I doubt AVG has anything to do with it.  

  Maybe you could try asking the same question on this forum http://www.geekzone.co.nz/forums.asp  , I have never experienced such a problem before so would be blind stabbing trying to diagnose it from afar.   

the stick works fine on others as well as this one ,,it only happens when shutting off pc next time you startup the msg occurs when the connection manager comes up ,,whats OS karen

  It might be worthwhile to download and run a registry cleaner. They can cause problems at times but it might help in this case.

I do not like fiddling with the registry but it might be at fault. 

He is using  Windows Vista/2008 

Don't do a registry cleaner unless you know what you are doing....

Did you uninstall the previous connection manager before installing the new one from the flashdrive?

Now that you have the software on flashdrive,  unplug the T-stick and try uninstalling from Control Panel:

have you tried a system restore to roll back the pc to an earlier point in time? not my fav way of resolving these issues but it comes in handy from time to time.

And DO NOT use a registry cleaner, most of the time they do more harm than good.

if you can get connected like you mentioned earlier, but have no data transfer, id recommend doing a ping test, go to start - run (or the search box in vista\windows 7) type cmd and press enter, type ping google.com press enter. you should get 4 replies like below

C:\Documents and Settings\Administrator>ping google.com

if you dont, then try pinging an ip address type ping 74.125.127.103 and press enter. If you get a reply from the IP address, but not the host name (google.com) you have a DNS problem, if you can ping both, its likely a browser issue, if you can ping neither it is likely something is blocking ports such as a firewall, or your TCP/IP stack could be bung.
