Uclassify Connector: Error FormatException

Trying to make use of the Uclassify Connector, have a list of keywords, after about 10 keywords I start to get the exception error:
Exception: FormatException
Message: Input string was not in a correct format

Every few lines then show #value! where the output should be

If I manually go back through,select the formula box, hit enter, the connector works. This makes me think some type of time-out error is happening. Is there any way to throttle back the calls or delay before it goes down the rows?

Example of the formula:

=Connector("uClassify.SimpleClassification","/browse/uclassify/health-topics","Text",A53,"Classification",TRUE)

Hi Jim,

What version of SeoTools are you using? We've recently implemented a request delay because of throttling which is probably what is causing your errors.

Im currently on the 7.0.30 version, downloaded just yesterday.
(32bit)

Can you try to set a delay manually under Settings? If you are using the free version it might help.

Assuming you mean the below, I did set this up, but still getting the same issues:

How many requests did you perform? I believe uClassify has a low limit for free accounts. When it is reached, it will generate errors continuously as new requests are freed up and used up.
