On Step 1, browse to ur launcher. (with the ... dots) to the right.
On Step 2, press check.
On Step 3, press backup.
On step 4, press the button.
Then use the new launcher it creates.
It'll make ur launcher able to use more then 3gb of memory.
Upgrading ur memory wont fix the problem, if u wont run this problem first.
If u only got 3gb, then u will need to increase ur RAM AND run this program.
