Mitesh,
There is a bug in it! You have to go into the control panel and adjust the balance control for the main volume. This bug is only in the freeware version. The one you buy doesn't have this bug. This drove me nuts like it is you. I like the version you buy better, unfortunatly you can only buy it by mail. The web site doesn't allow you to buy it online, you can download it, but can't buy it,, strange.
