Sorry, been busy and have not had time to check back in...
I made the assumption the skin was not in a subfolder... glad you got that corrected.
The UpdateRate on the webparser measure can be removed completely if you want, the default value is 600 (5 min). Setting it to anything lower is asking to get blocked by the website; hitting any site too often will look like an attack.
Also, a very low UpdateRate can cause the plugin to fail; multiple repeated calls of the webparser can cause problems. Re-starting Rainmeter usually corrects any errors.
Hopefully, this will get things working.
