Second PC loses connection

[BaghdadAssUp]

Hi, I am using the free trial for both computers atm before actually buying 2 copies.

Here's my problem:

I can get both keyclone working but after about 5-10 minutes, my second pc loses connection. For example, I have 3 WoW's open on my main, and 2 on my laptop. When I use my lightning bolt, it works fine. After 5-10 minutes of one-shotting mobs, my laptop's keyclone seems to have lost its connection. I check my laptop and it isn't connected to my main anymore. I try to reopen it and reconnect it and it does not work. The only fix to this is to close all my WoWs including both keyclones but even so, it only lasts 5-10 minutes at most! I have already googled the problem, but it was back in version 1.8j or so, I'm using 1.9i atm

Does anyone know a solution? I am also using Win7 64bit on both pcs

EDIT: I don't think I have explained properly. For example, PC1 is running Wow1, Wow2, Wow3 on keyclone. PC2 is remotely connected to PC1 running Wow4, Wow5. Keyclone works, I can have all my chars jump etc, BUT after 5-10 minutes of playing WoW, PC2 just stops responding. When I try to lightning bolt by pressing 2, only the chars on PC1 works whereas PC2 does not cast it. I run over to PC2 to cast lightning bolt and only the focused screen works, so keyclone stops working entirely for PC2. When trying to close both WoWs and keyclone and reopening them, it does not seem to work either.

I really want to set up 2 screens on my laptop as it runs really smoothly. If I cannot get help, can someone suggest another place where I could get help? Thanks.
