Error code 38 on entering cash shop

Me and a friend are having the same problem. The only reasoning that I thought of that makes sense is we tried to enter the cash shop when the sales switched, so "we're stuck in limbo". iirc, error 38 is EOF [end of file] meaning we're stuck in a coding error and need a server check to fix us.

I started getting this error on my main yesterday during the sales too, and this explanation would definitely make sense considering I was waiting on Black Friday sales.

I can log into the Cash Shop just fine on any other character on my account.
