SimpleSellr - Automatic eBay Spreadsheet

I opened this spreadsheet while my ebay account was open. HUGE MISTAKE. I never activated SimpleSellr, but now it's hijacked my ebay account and my internet tabs. I tried to delete this from googleDocs but it won't go away. I reached out to the makers and have't heard back. There's a SERIOUS BUG in this SPEADSHEET! I am jealous of the people who've given it great reviews but now I'm questioning if they're just bots who've written such positive reviews. THIS IS A NIGHTMARE. SERIOUSLY. BEWARE and DON'T USE IT

can not use it it keeps popping up when i login to anything and which no way to use it i dL everything it needs and still now i got this popping up blocking everything i can not do anything now i think i got go to factory setting soon i can not even find it to take out you stay it cant happen but it does i am trying to look for help not excuse OK now i got it but it disappeared its cool i like the concept but still learning
