Summer Teodosio

I had six thousand (here or there) in my online account.....I went to marketplace to check things out and bought USD $20 more linden which was around $4k. Now my account only shows the $4k and none of the linden I already had. Say what? Where are my other linden and how do I get it back? I am a long time player and took a break and am back now. Am I now to be taken as a fool? Advice is truly appreciated.

So this just happened. When I take my avatar to a dance or largely populated sim, my grahics get jumpy, my avatar jumps around, and I have trouble typing in the chat box because there is a delay.
