First, to make your life 100x easier, please refer to the answers given on this question to understand how to display Exceptions in English.
This change will allow you to Google exceptions and quickly find answers to problems your'e facing.

After you'll make this change, you'll get the following English exception:

Invalid value '2591982526.9035' for parameter 'interval'.

The reason for this error can be found in Timer.Interval documentation:

The time, in milliseconds, between Elapsed events. The value must be greater than zero, and less than or equal to MaxValue. The default is 100 milliseconds..

Since 2591982526.9035 is larger than Int32.MaxValue, which is 2147483647, you get an exception.
