Please help!
1. I got some links before, download and install PAC eWallet. It now doesn't open. Can come help by sending me a link where I can download and install the correct PAC Wallet?
2. I bought PAC coin in Cryptopia for weeks now. Do I have to transfer the coins to PAC wallet before January ends?
Any input from anyone is greatly appreciated.
You should download wallet from paccoin website
https://paccoin.net/The developers' advice was to move coins from Cryptopia to the personal wallet.
Do it before Feb 1; for the > 7% POS rewards (for coin age of up to 44 days from now.);
however, unless the PAC is taken out of maintenance mode @Cryptopia before Feb 1, there is no point in transferring the coins to a personal wallet unless you cannot trust Cryptopia. After that, you won't get the 7-10% POS staking/minting rewards anyway because the coin age needs to be more than 30 days for that purpose.

Wallet is under maintenance on cryptopia due to investigation of deposit issues
Please check the office FAQ site:

How long before I get a POS reward?
Your coins have to be in your wallet for at least 30 days before the stake and get a reward.
Do I earn rewards when my PC is offline?
No, you need to be online for POS rewards.
What happens after the 30 days?
Every 720 hours you will receive a 7-9% reward.
