Bitcoin Exchange Problems

I've been having difficulty lately buying/selling Bitcoin with Kraken. Today, I've attempted several times to sell my position but recieve an "Insufficeient Funds" or "Network Error" message when I do, and I HAVE the correct amount of funds in my account. When I attempt to contact Kraken about this using their contact form on the website (they no longer accept emails from personal accounts nor do they list a contact phone number), I recieve another "Network Error" message. Something really odd is happening with Kraken, for that reason I'm done using them.

I was wondering if any other Kraken users are having the same difficulties?

Also, are users of other exchanges expericing the same thing?
