Subsequent Events [Abstract]
Subsequent Events	Subsequent Events The Company was not able to make its April 30, 2018, payment to SWK due under the A&R Credit Agreement; therefore, the Company is in default with SWK and, due to the cross-default clause with CNH, was also in default on the 2016 Credit and Security Agreement. In addition, the Company's Subordinated Promissory Note owed to Century is subject to acceleration in the event SWK or CNH were to accelerate the Company’s obligations under the A&R Credit Agreement and 2016 Credit and Security Agreement. Due to the covenant violations, events of default, and the substantial doubt about the Company's ability to continue as a going concern, all debt has been classified as short-term on the condensed consolidated balance sheet as of March 31, 2018. On May 10, 2018, the Company signed the Fourth Amendment under which SWK has agreed to lend an additional $1.5 million (the “May 2018 Term Loan”) and forbear the outstanding payment and covenant defaults through June 1, 2018. The Company is working with SWK to complete a second forbearance agreement and related additional term loan for the period of June 1, 2018 through August 30, 2018 subject to additional terms and conditions as to be determined in its final form. SWK has not agreed to such a second forbearance agreement or additional term loan, and the Company can give no assurance that such agreements will be reached. Under the Fourth Amendment, the lender will provide the Company three advances under this agreement.as long as the Company is in compliance with the additional covenants set forth in the Fourth Amendment. The additional covenants require the Company to provide weekly updates to the approved cash flow forecast, keep actual expenses within 15% of budgeted amounts and engage a financial advisor to assist with identifying potential acquirers or investors and to effectuate a transition that results in a merger, acquisition or similar material investment. The Company has engaged Raymond James as its investment banker to advise and represent the Company as it seeks a Transaction to fulfill this requirement. All principal and accrued interest on the May 2018 Term loan and the August 2017 Term Loan will be due and payable on June 1, 2018. As a result of the cross-default, the Company also entered into the Forbearance Agreement through June 1, 2018 with CNH with respect to defaults under the 2016 Credit and Security Agreement subject to the same covenants as set forth in the Fourth Amendment with SWK. The Forbearance Agreement provides for CNH to continue to allow the Company to use an additional working capital overadvance of $0.3 million.
