I recently got the newer version of Bitcoin Core and it worked for 2 days and then it stopped working saying something with the network or something was wrong.
If you want help you should post the entire error message. "Something with network" is a bit vague.
Need help fast before I do any thing and also any thing to speed the sync of lite coin wallet?
You could use a "light wallet" e.g. electrum lite. If you want a wallet with the full blockchain you can use the bootstrap.dat
https://litecoin.info/Bootstrap.datbut if your bottleneck is the internet connection this will not make it faster.
