Hi Robert.

What OS are you using? Where is FSX installed?

Just changing each incidence of <Unlimited>0</Unlimited> to <Unlimited>1</Unlimited> should work. The line below it in the CSWeapon.xml file, <!-- unlimited ammo fire. 1-yes, 0-no -->, shows that it can be either 1 =yes = unlimited ammo or 0 = no = NO unlimited ammo, without causing it to not work. This is stated in the CSWeapon_SDK.pdf on page 5:

PARAMETERS DESCRIPTION
For convenience most of details on the CSWeapon.xml settings are listed right in the file comments. SDK
provides additional info on the parameters that have 'See SDK' mark in the comments.

With Windows Vista and 7 administrative rights can come into play. IF FSX is installed in its default location, C:\Program Files\etc..., then those operating systems have a tight hold on the programs within. I'm just saying this if that is the case. If not. Well it is something else going wrong. And then the only thing I can do is give out the modified CSWeapon.xml and ONLY that. And I will ONLY do that with Captain Sim permission.
